====== CRSF energy as function of luminosity ======

Many Cyclotron-line sources show a change in cyclotron line energy (Ecyc) as function of luminosity (Lx). Some theoretical explanation has been put forward by Becker et al. (2012), but a lot more work needs to be done. This plot here and the files below summarizes the observations so far.

===== FITS files =====
FITS files for individual sources. Typically the files have columns for time, luminosity (with uncertainties), cyclotron line energy (with uncertainty) and sometimes CRSF width (with uncertainty). The fundamental lines are denoted as "0", first harmonic as "1" and so on.
See header for references and energy band of the luminosity.

For questions or updates contact [mailto:ff@caltech.edu Felix].

The files are currently hosted at Caltech, as the Wiki doesn't allow FITS format in its media database. If you have a better solution, let me know. <br />— ''[mailto:Felix.Fuerst@sternwarte.uni-erlangen.de Felix Fürst] 2015-05-14 20:28''
