The HEASARC and NuSTAR teams are greatly saddened by the sudden passing of Katja Pottschmidt. Most recently Katja was the lead scientist for the NuSTAR Guest Observer Facility (GOF), a role she had supported for many years. During her science career she worked on many other high energy astrophysics missions and played an integral role in advancing our knowledge of the universe. She was a wonderful colleague and friend and will be keenly missed by all who knew her.
HEASoft and XSPEC are now available as conda packages. See details ....
XSTAR warm absorber model
An analytic model for calculating warm absorber spectra within xspec is available. This has the advantage over the xstar table models that it avoids the intrinsic approximations associated with use of tables for absorption with variable abundances treated as multiplicative parameters, and the intrinsic clumsiness of the use of tables. It also allows the use of arbitrary spectral resolution, not limited by the internal xstar spectral resolution. To use it, go to the xstar page and follow the instructions there. Please send reports of bugs and problems to tim-at-xstar.gsfc.nasa.gov.
