More models for XSPEC
The following models have been publically released by their authors
but are not included in the latest release. Those that are
table models can simply be downloaded and used in XSPEC using the
Other models can be installed as local models as described in the
Some of these models are available through GitHub.
If you have models that you would like to make available to a wider
public, please contact Keith Arnaud (Keith.A.Arnaud-at-nasa.gov).

variable-Comptonization spectral-timing model for QPOs: vKompth
Model added on 8/11/23.
reflection model from Dauser and Garcia which combines relconv and xillver: relxill.
For Mac OS users attempting to build the relxill local model
package (using Xspec's 'initpackage' command) with the clang++ compiler, you will first need to download and run
this shell script from your
heasoft-[ver]/Xspec/src directory. Note that this is the same
directory from which you would normally install Xspec patch files.
