Making tables with sltable

2019-05-07T16:09:10Z

Hemphill: corrected a malformed <pre></pre> tag

<code>sltable()</code> is a function designed to streamline the production of LaTeX tables from ISIS data structures. It's put together with the intent of being able to go from a single call to <code>get_params()</code> to a functional LaTeX table in as few steps as possible.

The following examples all start from files saved with the <code>save_par()</code> function, but note that <code>sltable()</code> does not require that you start from here: as explained in the documentation, <code>sltable()</code> is perfectly happy to work with arrays of numbers or strings, or any struct with a "value" field. The function is thus not limited to spectral fits, although spectral fits are what were in mind when it was written.

The basic structure of a call to <code>sltable()</code> is
<pre>
table = sltable(par1, par2, ...; <qualifiers>);
</pre>
Each argument given to <code>sltable()</code> is interpreted as one column of the table (or one row if the "horiz" qualifier is nonzero). The arguments can be arrays of strings, which will be printed as-is, arrays of numbers, which will be rounded to three sig figs, or structs. Structs should be of the form:
<pre>
struct{value,min,max,freeze,limit,nodata}
</pre>
Only the "value" field is strictly needed; "min" and "max" fields will be used to determine and format error bars, the "freeze" field can be used to specify when a value is frozen, and a "limit" field can be used to indicate whether a value's uncertainties reaching zero is "important" or not (e.g., a power-law's normalization should have "limit=1" set, a power-law's photon index should not). The "nodata" field will cause a <tt>\nodata</tt> symbol to be printed (or whatever you specify in the "nodata" qualifier in your call to <tt>sltable()</tt>). This is useful if you want to, e.g., have different models in the same table.

Structs can be provided either as an array of structs (as returned by, e.g., <tt>get_params()</tt>) or a struct with arrays for its fields. That is, the following two commands produce the same output:
<pre>
isis> t1 = sltable(struct{value=[1,2,3]});
isis> t2 = sltable([struct{value=1},struct{value=2},struct{value=3}]);
isis> if(t1 == t2) print("Tables match!");
"Tables match!"
</pre>
Note that <code>sltable([1,2,3])</code> also produces the same output as the above two commands. However, with structs you can do much fancier things. Consider:
<pre>
isis> sltable([struct{value=1},struct{value="foo"}],[struct{value="bar"},struct{value=3,min=2,max=4}]);
\begin{deluxetable}{lr}
\tabletypesize{\footnotesize}
\tablewidth{0pt}
\tablecaption{\label{placeholder}}
\tablehead{}
\startdata
$1.00$ & bar \\
foo & $3.0\pm1.0$ \\
\enddata
\end{deluxetable}
</pre>
Since arrays of structs don't need their "value" fields to have the same type - and indeed can have different fields present entirely - we can have different datatypes in different cells, some values, some text, some values with uncertainties.

Next, I'll give a set of more practical examples.

=== A simple example: Just the numbers ===
Say you have a set of best-fit parameters saved in the file <tt>best.err</tt>, with error bars found via, e.g., <tt>conf_loop()</tt> and saved with <tt>save_par()</tt>. The file looks like this:

<pre>
tbnew_feo(1)*(enflux(1,powerlaw(1)*highecut(1))+gaussian(1)+gaussian(2))
idx param tie-to freeze value min max
1 tbnew_feo(1).nH 0 0 0.513343 0 4.444283 10^22
2 tbnew_feo(1).O 0 1 1 0 5
3 tbnew_feo(1).Fe 0 1 1 0 5
4 tbnew_feo(1).redshift 0 1 0 0 10
5 powerlaw(1).norm 0 1 1 0 1e+10
6 powerlaw(1).PhoIndex 0 0 0.3860679 0.3028138 0.5389627
7 highecut(1).cutoffE 0 0 13.12143 12.53526 13.6398 keV
8 highecut(1).foldE 0 0 8.823162 8.057953 9.841905 keV
9 enflux(1).enflux 0 0 0.003303485 0.003174848 0.003634531 keV/s/cm^2
10 enflux(1).E_min 0 1 3 0 1e+20 keV
11 enflux(1).E_max 0 1 10 0 1e+20 keV
12 gaussian(1).norm 0 0 5.302337e-05 3.990932e-05 6.566915e-05
13 gaussian(1).LineE 0 0 6.477083 6.428396 6.480077 keV
14 gaussian(1).Sigma 0 0 1e-06 1e-06 0.445422 keV
15 gaussian(2).norm 0 0 0.0001028086 8.738482e-05 0.0001178745
16 gaussian(2).LineE 0 0 6.572322 6.524679 6.628665 keV
17 gaussian(2).Sigma 0 0 0.3808866 0.3268635 0.4454205 keV
</pre>

In ISIS, to turn this into a LaTeX table, the simplest thing we could do is:

<pre>
isis> load_par("best.err");
isis> variable t = sltable(get_params());
isis> variable f = fopen("example.tex","w+");
isis> () = fputs(t,f);
isis> () = fclose(f);
</pre>

Note that <tt>sltable()</tt> returns the entire table as a variable, which we then write to a file using <tt>fputs()</tt>. After calling this code, <tt>example.tex</tt> looks like this:

<pre>
\begin{deluxetable}{l}
\tabletypesize{\footnotesize}
\tablewidth{0pt}
\tablecaption{\label{placeholder}}
\tablehead{}
\startdata
$< 4.44$ \\
$(1.00)$ \\
$(1.00)$ \\
$(0.000)$ \\
$(1.00)$ \\
$0.39^{+0.16}_{-0.09}$ \\
$13.1\pm0.6$ \\
$8.8^{+1.1}_{-0.8}$ \\
$0.00330^{+0.00034}_{-0.00013}$ \\
$(3.00)$ \\
$(10.0)$ \\
$\left(5.3^{+1.3}_{-1.4}\right)\times10^{-5}$ \\
$6.4771^{+0.0030}_{-0.0487}$ \\
$(0.00000100)$ \\
$\left(1.03\pm0.16\right)\times10^{-4}$ \\
$6.57^{+0.06}_{-0.05}$ \\
$0.38^{+0.07}_{-0.06}$ \\
\enddata
\end{deluxetable}
</pre>
which, when dropped into a proper LaTeX document, results in the following table:

[[File:very_simple_table.png|200px]]

This is not a particularly fancy-looking table, but it gets the essential bits: numbers, in the right places, with error bars, and some sort of indication when a parameter is frozen.

=== A slightly less simple example: A table with row and column names ===

With a little extra work, we can make this look better:
<pre>
isis> load_par("best.err");
isis> variable parndx = [1,[6:9],[12:17]]; % select which parameters we want in the table
isis> variable p = get_params(parndx);
isis> variable rownames = array_struct_field(p,"name"); % get the names of the parameters for the row names
isis> rownames = array_map(String_Type,&strreplace,rownames,"_","\\_"); % Change _ to \_ so LaTeX doesn't complain
isis> variable colnames = ["Parameter","Value"];
isis> variable lab = "tab:example"; % the label that the table with receive
isis> variable caption = "Example table!"; % the caption for the table
isis> variable t = sltable(p;rownames=rownames,label=lab,caption=caption);
isis> variable f = fopen("example.tex","w+");
isis> () = fputs(t,f);
isis> () = fclose(f);
</pre>
This results in the following LaTeX file:
<pre>
\begin{deluxetable}{lr}
\tabletypesize{\footnotesize}
\tablewidth{0pt}
\tablecaption{The best-fit parameters\label{tab:best}}
\tablehead{\colhead{Parameter}&\colhead{Value}}
\startdata
tbnew\_feo(1).nH & $< 4.44$ \\
powerlaw(1).PhoIndex & $0.39^{+0.16}_{-0.09}$ \\
highecut(1).cutoffE & $13.1\pm0.6$ \\
highecut(1).foldE & $8.8^{+1.1}_{-0.8}$ \\
enflux(1).enflux & $0.00330^{+0.00034}_{-0.00013}$ \\
gaussian(1).norm & $\left(5.3^{+1.3}_{-1.4}\right)\times10^{-5}$ \\
gaussian(1).LineE & $6.4771^{+0.0030}_{-0.0487}$ \\
gaussian(1).Sigma & $(0.00000100)$ \\
gaussian(2).norm & $\left(1.03\pm0.16\right)\times10^{-4}$ \\
gaussian(2).LineE & $6.57^{+0.06}_{-0.05}$ \\
gaussian(2).Sigma & $0.38^{+0.07}_{-0.06}$ \\
\enddata
\end{deluxetable}
</pre>
which looks like this once compiled:

Much nicer!

=== A significantly less simple example: Multiple datasets, same model ===
Often we want to include tables with multiple sets of parameters - for example, you have multiple observations fit with the same model, and you want to show them all in the same table. I have four files, <tt>10145-01-01-00.par</tt>, <tt>20146-07-02-00.par</tt>, <tt>50067-03-01-00.par</tt>, and <tt>80016-02-01-00.par</tt>, which have the best-fit parameters with uncertainties for four RXTE observations of the HMXB 4U 1538-522. They all look something like this:
<pre>
constant(Isis_Active_Dataset)*tbnew_feo(1)*(enflux(1,powerlaw(1)*highecut(1)*gauabs(1)*gauabs(2))+egauss(1)+egauss(2))

To make a table with all four, I have the following script:
<pre>
variable obs = ["10145-01-01-00","20146-07-02-00","50067-03-01-00","80016-02-01-00"];
variable i;
% We need to load some data so the model parameters can be loaded. Literally
% any set of two spectra will work just fine - this is just so the
% constant(Isis_Active_Dataset) component can be loaded properly.
clear_all(;noprompt);
load_data("/opt/data/rxte/H1538/phase_averaged/103-123/10145_pca_103-123.pha");
load_data("/opt/data/rxte/H1538/phase_averaged/103-123/10145_hexte_103-123.pha");
% The arrays of structs will be stored in a list:
variable p = list_new();
% These are the indices of the parameters I want to include in the table, in
% the order I want them to appear:
variable parndx = [16,25,2,[7:12],19,22];
% Here are fancy names for the parameters listed in parndx:
variable parname = ["Flux","$C_{\\rm HEXTE}$","$N_{\\rm H}$",
"$\\Gamma$","$E_{\\rm cut}$","$E_{\\rm fold}$",
"$E_{\\rm cyc}$","$\\sigma_{\\rm cyc}$","$\\tau_{\\rm cyc}$",
"$A_{\\rm Fe}$","$A_{\\rm smooth}$"];
% And their units:
variable parunits = ["keV\\,cm$^{-2}$\\,s$^{-1}$","","$\\times 10^{22}$\,cm$^{-2}$",
"","keV","keV","keV","keV","","$\\times 10^{-4}$\\,ph\\,cm$^{-2}$\\,s$^{-1}$",
"$\\times -10^{-4}$\\,ph\\,cm$^{-2}$\\,s$^{-1}$"];
% Loop through the observations, loading the parameters, doing some processing
% and rescaling to make things look better on the page, and storing them in the
% list:
_for i (0,length(obs)-1,1) {
load_par(obs[i]+".par");
variable ptemp = get_params(parndx);
% The iron line and "smoothing" Gaussian (egauss(1) and egauss(2)) get scaled
% up by 1e4 (note that I've noted that in their units above)
ptemp[-2].value *= 1e4;
ptemp[-2].min *= 1e4;
ptemp[-2].max *= 1e4;
% The "smoothing" Gaussian additionally has a negative normalization - we
% flip the sign here (this means we need to swap the min and max fields, too)
ptemp[-1].value *= -1e4;
ptemp[-1].min *= -1e4;
ptemp[-1].max *= -1e4;
variable temp = @ptemp[-1].max;
ptemp[-1].max = @ptemp[-1].min;
ptemp[-1].min = temp;
% "ptemp" is an array of structs, which we append to the list "p"
list_append(p,ptemp);
}

% Note the use of __push_list() to push the list "p" onto the stack. This is
% the equivalent of writing "sltable(p[0],p[1],p[2],p[3])", but with the
% advantage that it works no matter how many elements "p" has.
variable t = sltable(__push_list(p);
rownames = {parname,parunits}, % a List_Type here is interpreted as parameter names and units
colnames = obs, % names for columns
notes = {["Energy frozen to 6.4\\,keV, width frozen to 0.01\\,keV"],["*"]}, % note use of List_Type here too
caption = "Fits to 4U~1538$-$522 for four \\textit{RXTE} ObsIDs", % caption
label = "tab:multiple"); % label

% Write the table to a file
variable f = fopen("multiple.tex","w+");
() = fputs(t,f);
() = fclose(f);
</pre>

This is quite a bit of code, but the actual code to make the table itself is, again, only one line. The resulting <tt>multiple.tex</tt> file looks like this:
<pre>

Two things to note here: <tt>sltable()</tt> will produce one column of numbers for each array of structs you give it, so the use of a list variable and push_list lets us make tables with arbitrary numbers of columns fairly easily. Second, the "notes" qualifier takes a two-element <tt>List_Type</tt>: the first element is an array of string containing the text of the notes, and the second element is an array of strings containing the symbols for those notes.

The table, once compiled with LaTeX, looks like this:

[[File:sltable_multi_obs_table.png|650px]]

For a good time, try adding the qualifiers "horiz=1,landscape=1" and swapping the "rownames" and "colnames" qualifiers. You should get something like this:

[[File:sltable_multi_obs_table_horiz.png|1050px]]

There is one issue, which is that the footnote should be accompanied by a marker on the iron line area (i.e., <tt>A_Fe</tt> should have an asterisk next to it). I haven't figured out a sensible way to approach this, so right now you'll have to add those in by hand.

=== A decidedly not simple example: Multiple different models ===
If you are making a table with multiple models (that is, models with different sets of parameters), you need to inform <tt>sltable()</tt> that it needs to plot rows where some columns have no data. This is where the "nodata" field for the input structure comes into play.

Say you have an array of parameter names (or some sort of identifier; let's call that variable <tt>parnames</tt>) that you want to include in a table, and you have arrays of structures returned by <tt>get_params()</tt> from a few different models (let's call those <tt>m1</tt> and <tt>m2</tt> here). The way I've approached this is to create a new list of arrays of structures, <tt>tableParams</tt>, that will be the input to <tt>sltable()</tt>, with extra rows with the "nodata" field set to 1 for missing parameters. We loop over all the parameters, and if the parameter is included in the model, we copy that structure into <tt>tableParams</tt>; if the parameter is not present, we set that element of <tt>tableParams</tt> to a structure with <code>nodata = 1</code>.
<pre>
variable i,j;
variable models = {m1,m2};
variable modelNames = ["model 1","model 2"];
variable nModels = length(models);
variable tableParams = List_Type[nModels];
_for j (0,nModels-1,1) {
_for i (0,length(parnames)-1,1) {
if(length(where(array_struct_field(models[j],"name") == parnames[i])) == 1) {
tableParams[j][i] = struct_copy(models[j][i]);
} else {
tableParams[j][i] = struct{value=0.0,nodata=1};
}
}
variable t = sltable(__push_list(tableParams);rownames=array_struct_field(tableParams[0],"name"),colnames=modelNames);
</pre>

You could do this with a 1D or 2D array of structures, but I find the "list of arrays" approach is easier to keep track of (and it's not like efficiency is incredibly important for this task anyway...).

By default this outputs a <tt>\nodata</tt> command for <tt>deluxetable</tt> tables and an <tt>\ldots</tt> command for a <tt>tabular</tt> table, but you can customize this by setting the <tt>nodata</tt> qualifier for <tt>sltable()</tt> to your preferred string.

= Gaia Distances =
'''NOTE: The distances here are for the Gaia source that is ''closest'' to the SIMBAD position for each object. This means that for objects with poorly-determined positions or no identified optical counterpart, the distance is ''INCREDIBLY SUSPECT''.''' Until someone has time to go through source-by-source and clean this up, ''you'' need to check carefully whether the ''Gaia'' source ID listed here ''actually corresponds'' to the object you are looking at.
The parallaxes are converted to distance by Bailer-Jones et al. (see [https://ui.adsabs.harvard.edu/#abs/2018arXiv180410121B/abstract this paper] and [http://www.mpia.de/homes/calj/gdr2_distances/main.html this webpage]). Again, these should be taken with a hefty grain of salt and are dependent on the priors selected by Bailer-Jones et al.

= Correlation between luminosity and CRSF energy =
In recent years more and more sources have been observed at different luminosities, allowing us to find correlation between the luminosity and the cyclotron line energy. A summary of the current state of the observations can be found on this page:
[[CRSF energy as function of luminosity]]

= Assignments =
Our collaboration has assigned one or two sources to each member to take care of, i.e., to put together the most important information and keep the page up to date in case new data are available or new papers are published. [[X-ray pulsar assignments|The list]] can only be accessed if logged in.

The following table describes parallax distances as computed by Bailer-Jones et al. (see [https://ui.adsabs.harvard.edu/#abs/2018arXiv180410121B/abstract this paper] and [http://www.mpia.de/homes/calj/gdr2_distances/main.html this webpage]). Note that these should be taken with a hefty grain of salt and are dependent on the priors selected by Bailer-Jones et al. - as an example, the Magellanic cloud sources show up in Gaia DR2 as having distances of ~7 kpc, when they are actually 45 or 60 kpc away.

= Correlation between luminosity and CRSF energy =
In recent years more and more sources have been observed at different luminosities, allowing us to find correlation between the luminosity and the cyclotron line energy. A summary of the current state of the observations can be found on this page:
[[CRSF energy as function of luminosity]]

= Assignments =
Our collaboration has assigned one or two sources to each member to take care of, i.e., to put together the most important information and keep the page up to date in case new data are available or new papers are published. [[X-ray pulsar assignments|The list]] can only be accessed if logged in.

The following table describes parallax distances as computed by Bailer-Jones et al. (see [https://ui.adsabs.harvard.edu/#abs/2018arXiv180410121B/abstract this paper] and [http://www.mpia.de/homes/calj/gdr2_distances/main.html this webpage]). Note that these should be taken with a hefty grain of salt and are dependent on the priors selected by Bailer-Jones et al. - as an example, the Magellanic cloud sources show up in Gaia DR2 as having distances of ~7 kpc, when they are actually 45 or 60 kpc away.

= Available data =

To be filled in later.

= Background =

The accreting X-ray pulsar, 4U 1538-522, has been observed by every
X-ray satellite since UHURU, and quite possibly was detected
in earlier rocket <ref name="Friedman67" />, balloon <ref name="Lewin68" />, and
satellite <ref name="Hudson69" /> observations. <ref name="Davidson77b" /> and
<ref name="Becker77" /> discovered pulsations at 528 s from a source
designated A1540-53, whose position was later updated to be coincident
with 4U 1538-522 <ref name="Davidson77" />. <ref name="Becker77" /> used the 9 day
OSO-8 observation to derive a 3.73 day orbital period from
the Doppler modulation of the observed pulse period. <ref name="Apparo78" />
localized the source to 40" with SAS-3, and then <ref name="Schwartz78" />
further refined the position error box to #12'' with HEAO-1,
thereby reducing the number of candidate optical counterparts noted in
<ref name="Cowley77" /> to a single one -- #12, a B0 supergiant designated as
QV Nor. Independently, <ref name="Parkes78" /> obtained spectra of the stars
in the SAS-3 error circle and identified star 12 to be the
counterpart of 4U 1538-522. Later photometric observations by
<ref name="Crampton78" /> detected the 3.73 d orbital variability in the
absorption and emission line radial velocity curves. A mass estimate
from the X-ray and optical data yields a neutron star mass
Mx=1.06+0.41-0.34
Msol and companion star mass Mopt=16.4+5.2-4.0 Msol
<ref name="vKerkwijk95" />. The 4U 1538-522 system is similar to other high mass
X-ray binary systems, such as Vela X-1 <ref name="Kreykenbohm08" /> and
4U 1907+09 <ref name="IntZand98" />,<ref name="Fritz06" />, with long pulse periods (hundreds of
seconds), short orbital periods (<10 days), and flaring.
The spin and orbital periods place 4U 1538-522 among the
X-ray binary systems with a supergiant companion that underfills its Roche
lobe.

= The Present Situation =

== Timing ==

Until the launch of the BATSE instrument, the sparse
satellite-by-satellite pulse period measurements had shown that
4U 1538-522 had been spinning down. Somewhere in the mid to late 1980's
this trend reversed and continuous BATSE measurements over 8 years
revealed a continuous spin-up trend <ref name="Rubin97" />. This trend has
continued at least through 2003, e.g. RXTE results <ref name="Baykal06" />.
The recent spin frequency measurements by the GBM on the Fermi
satellite [[http://gammaray.nsstc.nasa.gov/gbm/science/pulsars/lightcurves/4u1538.html]]
shows that the source underwent another torque reversal in 2008 (approximately) and has been spinning down since. The current pulse period is approximately 526.1 s.

== Spectrum ==

Initial descriptions of the spectrum included a power law modified at
low energies by photoelectric absorption plus an iron line, and at
high energies by a cutoff to an exponential shape,
e.g. <ref name="White83" />. A cyclotron resonant scattering feature
(CRSF or cyclotron line) at 20 keV was discovered by
<ref name="Clark90" /> from Ginga observations, which also showed a
modulation in the cyclotron line strength and centroid with pulse
phase. Broad band spectra were obtained in 1998 using
BeppoSAX <ref name="Robba01" />, and in 1997/2001 using RXTE
<ref name="Coburn02" />. The cyclotron line was detected at ~21 keV with a marginal indication
of a second feature at 51+4-3 keV from BeppoSAX
<ref name="Robba01" />. Phase-resolved spectroscopy by RXTE in
8 broad phase bins <ref name="Coburn02" /> revealed that the
cyclotron line centroid exhibited maxima coincident with the two pulse
peaks, which may be an indication of emission from both magnetic
poles. In addition, the power law index was seen to be flatter on the
falling portions of the pulse peaks, as has been seen in other pulsars.
The pulsed light curve from RXTE
showed significant energy-dependent structure, including a single,
broad, flat-topped main pulse which narrowed above 10 keV, a second
smaller pulse above 2 keV, and variation in the shape of the secondary
pulse with increasing energy <ref name="Coburn02" />.

All distances with uncertainties are from Gaia data release 2, as described by Bailer-Jones et al. (see [https://ui.adsabs.harvard.edu/#abs/2018arXiv180410121B/abstract this paper] and [http://www.mpia.de/homes/calj/gdr2_distances/main.html this webpage]). Note that these should be taken with a grain of salt and are dependent on the priors selected by Bailer-Jones et al. - as an example, the Magellanic cloud sources show up in Gaia DR2 as having distances of ~7 kpc, when they are actually 45 or 60 kpc away.

The figure below displays the position of accreting X-ray pulsars in the Galaxy as far as known at this moment. Click on the figure for a larger version. Labels indicate the ordinal number in the first column of the table. Uncertainties in the distances are not indicated. Empty symbols represent sources for which there is no distance info in the literature; they have been artificially set to a distance of 7.6 kpc. [http://heasarc.gsfc.nasa.gov/W3Browse/catalog/class.html HEASARC source class identifiers] are also given. The spiral arms are from Vallée et al. (2008)<ref name="Vallee08" />.

= Correlation between luminosity and CRSF energy =
In recent years more and more sources have been observed at different luminosities, allowing us to find correlation between the luminosity and the cyclotron line energy. A summary of the current state of the observations can be found on this page:
[[CRSF energy as function of luminosity]]

= Assignments =
Our collaboration has assigned one or two sources to each member to take care of, i.e., to put together the most important information and keep the page up to date in case new data are available or new papers are published. [[X-ray pulsar assignments|The list]] can only be accessed if logged in.

Distances with uncertainties are from Gaia data release 2, as described by Bailer-Jones et al. (see [https://ui.adsabs.harvard.edu/#abs/2018arXiv180410121B/abstract this paper] and [http://www.mpia.de/homes/calj/gdr2_distances/main.html this webpage]). Note that these should be taken with a grain of salt and are dependent on the priors selected by Bailer-Jones et al. - as an example, the Magellanic cloud sources show up in Gaia DR2 as having distances of ~7 kpc, when they are actually 45 or 60 kpc away.

= Location in the Galaxy =

The figure below displays the position of accreting X-ray pulsars in the Galaxy as far as known at this moment. Click on the figure for a larger version. Labels indicate the ordinal number in the first column of the table. Uncertainties in the distances are not indicated. Empty symbols represent sources for which there is no distance info in the literature; they have been artificially set to a distance of 7.6 kpc. [http://heasarc.gsfc.nasa.gov/W3Browse/catalog/class.html HEASARC source class identifiers] are also given. The spiral arms are from Vallée et al. (2008)<ref name="Vallee08" />. Figure and data provided by Arash Bodaghee, SSL, UC Berkeley.

= Correlation between luminosity and CRSF energy =
In recent years more and more sources have been observed at different luminosities, allowing us to find correlation between the luminosity and the cyclotron line energy. A summary of the current state of the observations can be found on this page:
[[CRSF energy as function of luminosity]]

= Assignments =
Our collaboration has assigned one or two sources to each member to take care of, i.e., to put together the most important information and keep the page up to date in case new data are available or new papers are published. [[X-ray pulsar assignments|The list]] can only be accessed if logged in.

Distances with uncertainties are from Gaia data release 2, as described by Bailer-Jones et al. (see [https://ui.adsabs.harvard.edu/#abs/2018arXiv180410121B/abstract this paper] and [http://www.mpia.de/homes/calj/gdr2_distances/main.html this webpage]). Note that these should be taken with a grain of salt and are dependent on the priors selected by Bailer-Jones et al. - as an example, the Magellanic cloud sources show up in Gaia DR2 as having distances of ~7 kpc, when they are actually 45 or 60 kpc away.

= Location in the Galaxy =

The figure below displays the position of accreting X-ray pulsars in the Galaxy as far as known at this moment. Click on the figure for a larger version. Labels indicate the ordinal number in the first column of the table. Uncertainties in the distances are not indicated. Empty symbols represent sources for which there is no distance info in the literature; they have been artificially set to a distance of 7.6 kpc. [http://heasarc.gsfc.nasa.gov/W3Browse/catalog/class.html HEASARC source class identifiers] are also given. The spiral arms are from Vallée et al. (2008)<ref name="Vallee08" />.

= Correlation between luminosity and CRSF energy =
In recent years more and more sources have been observed at different luminosities, allowing us to find correlation between the luminosity and the cyclotron line energy. A summary of the current state of the observations can be found on this page:
[[CRSF energy as function of luminosity]]

= Assignments =
Our collaboration has assigned one or two sources to each member to take care of, i.e., to put together the most important information and keep the page up to date in case new data are available or new papers are published. [[X-ray pulsar assignments|The list]] can only be accessed if logged in.

= Location in the Galaxy =

The figure below displays the position of accreting X-ray pulsars in the Galaxy as far as known at this moment. Click on the figure for a larger version. Labels indicate the ordinal number in the first column of the table. Uncertainties in the distances are not indicated. Empty symbols represent sources for which there is no distance info in the literature; they have been artificially set to a distance of 7.6 kpc. [http://heasarc.gsfc.nasa.gov/W3Browse/catalog/class.html HEASARC source class identifiers] are also given. The spiral arms are from Vallée et al. (2008)<ref name="Vallee08" />. Figure and data provided by Arash Bodaghee, SSL, UC Berkeley.

= Correlation between luminosity and CRSF energy =
In recent years more and more sources have been observed at different luminosities, allowing us to find correlation between the luminosity and the cyclotron line energy. A summary of the current state of the observations can be found on this page:
[[CRSF energy as function of luminosity]]

= Assignments =
Our collaboration has assigned one or two sources to each member to take care of, i.e., to put together the most important information and keep the page up to date in case new data are available or new papers are published. [[X-ray pulsar assignments|The list]] can only be accessed if logged in.

= Correlation between luminosity and CRSF energy =
In recent years more and more sources have been observed at different luminosities, allowing us to find correlation between the luminosity and the cyclotron line energy. A summary of the current state of the observations can be found on this page:
[[CRSF energy as function of luminosity]]

= Assignments =
Our collaboration has assigned one or two sources to each member to take care of, i.e., to put together the most important information and keep the page up to date in case new data are available or new papers are published. [[X-ray pulsar assignments|The list]] can only be accessed if logged in.

The figure below displays the position of accreting X-ray pulsars in the Galaxy as far as known at this moment. Click on the figure for a larger version. Labels indicate the ordinal number in the first column of the table. Uncertainties in the distances are not indicated. Empty symbols represent sources for which there is no distance info in the literature; they have been artificially set to a distance of 7.6 kpc. [http://heasarc.gsfc.nasa.gov/W3Browse/catalog/class.html HEASARC source class identifiers] are also given. The spiral arms are from Vallée et al. (2008)<ref name="Vallee08" />. Figure and data provided by Arash Bodaghee, SSL, UC Berkeley.

= Correlation between luminosity and CRSF energy =
In recent years more and more sources have been observed at different luminosities, allowing us to find correlation between the luminosity and the cyclotron line energy. A summary of the current state of the observations can be found on this page:
[[CRSF energy as function of luminosity]]

= Assignments =
Our collaboration has assigned one or two sources to each member to take care of, i.e., to put together the most important information and keep the page up to date in case new data are available or new papers are published. [[X-ray pulsar assignments|The list]] can only be accessed if logged in.
