More models for XSPEC

The following models have been publically released by their authors but were not included in the latest release (12.7.1). Those that are table models can simply be downloaded and used in XSPEC using the atable or mtable commands. Other models can be installed as local models.

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). This page was last updated on October 25th, 2012.
