Change-Log of the RELLINE model:
- 2013-03-19: Version v0.4c. The environment variable "RELLINE_TABLES" can now be used to set the path to the relline tables individually.
- 2013-02-22: Version v0.4b. Finally, the height of the lamp post source can also be fitted for values smaller than 3rg, as close as 10% away from the event horizon of the black hole.
- 2012-09-12: Version v0.4a. Leaving the previous models (RELLINE, RELLINE_LP, RELCONV, and RELCONV_LP) untouched, this major update adds the implementations RELCONV_LP_EXT, RELCONV_LP_EXT. With these models the irradiation of the accretion disk by radially extended jets with an eventual velocity gradient can be calculated. More details on these more complicated source geometries will soon be presented in a paper (Dauser et al., 2013).
- 2012-03-19, version v0.3b: The new Headas 6.12 now uses the flag "pedantic", which prevented the code from compiling. This was fixed now. Moreover the lamp post part of the model still contained a bug: Due to a confusion between the spectral and photon index, the emissivity at the very inner edge was over-predicted. This effects only fits for very high spin and low heights of the primary source.
- 2012-01-23, version v0.3a: Thanks to Keigo Fukumura I realized that assumptions made in the lamp post model were not completely correct. I neglected the influence of a different power law index of the primary source. As it seems, for high spin and low heights there are indeed changes present. Instead of having always a power law index of 2 assumed, this parameter has now to be specified in the model. Note that previous saved parameter-model-files are not compatible with the lamp post model in the new version, as the additional parameter "gamma" was introduced in the current version.
- 2011-12-08, version v.0.2c: Caching was implemented for all routines (relline and relconv). In combination with typical models (powerlaw, absorption, ...) this can speed up fitting by a factor of 3 and more. Moreover, the relconv code was extremely trimmed regarding speed, i.e., for large numbers of grid points the calculation can be up to a factor of 6 faster now.
- 2011-10-17, version v.0.2b: Minor index bug in the convolution code was revealed thanks to Jeremy Sanders: The intrinsic energy grid was shifted by one bin (2-5eV), which should not have affected any data analysis due to the smallness of the shift. Moreover the code was sped up a little. Files which changed are relbase.f90 and relconv.f90.
- 2011-07-19: The version v0.2 is released. Two additional implementations of the model now include the lamp post geometry. In this geometry the primary hard photons causing the reflection are not assumed to originate from a hot corona above the disk, but to be emitted from a stationary source on the rotational axis of the black at height h. More details will soon be presented in a paper (Dauser et al., in prep).
- 2011-05-18: New fits-table calculated (v0.1f), as a bug in the code for calculating the table resulted in slightly different shapes, if the spin is negative and the inclination angle is high. Thanks to Michal Dovciak for realizing this problem and showing that the line profiles for negative spin are now in agreement with the ky-type models (Dovciak et al, 2004).
- 2011-02-25: Bug fixed which prevented the correct usage of a "negative" Rbr, i.e., a Rbr given in units of the ISCO. My thanks to Norbert Schartel for noticing that.
- 2010-10-04: compatibility problem solved that prevented relline from being used simultaneously with warmabs or the ky-type models. My thanks to Roderick Johnstone for pointing this issue out to me.
- 2010-09-29: the redshift parameter z was implemented wrong, which is corrected in the current version (v0.1c) of relline.f90. (special thanks to Francesco Tombesi for noticing that)
- 2010-09-29: table.fits.gz calculates now slightly better line profiles for low inclination angles (< 15 deg)
- 2010-08-02: RELCONV can now be used with a virtually extended response matrix
- 2010-08-02: with the new compile.csh the path to the fits-table is set to the current directory and thus the model can now be loaded from any directory
