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.

absori: ionized absorber
An ionized absorber based on that of Done et al. (1992,
ApJ 395, 275)
and developed by Magdziarz & Zdziarski (1995, MNRAS 273,
837). See
also Zdziarski et al. (1995, ApJ 438,
L63). Photoionization
rates are from Reilman & Manson (1979, ApJS 40, 815), who
employ the Hartree-Slater approximation (accurate to about 5%), and
recombination rates are from Shull & van Steenberg (1982, ApJS
48, 95). The cross sections are extrapolated with 
above 5
keV. The abundances are set up by the command abund. Send questions or
