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.

nteea: non-thermal pair plasma
A nonthermal pair plasma model based on that of Lightman & Zdziarski (1987) from Magdziarz and Zdziarski. It includes angle-dependent reflection from Magdziarz & Zdziarski (1995). In versions 1.1 and above the Compton reflection is done through an internal call to the reflect model. The Greens' function integration required for the Compton reflection calculation is performed to an accuracy of 0.01 (i.e. 1%). This can be changed using e.g. xset NTEEA_PRECISION 0.05.The abundances are set up by the command abund. Send questions or comments to aaz@camk.edu.pl
