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.

dust: dust scattering
A modification of a spectrum due to scattering off dust on the line-of-sight.
The model assumes that the scattered flux goes into a uniform disk whose
size has a 1/E dependence and whose total flux has a 1/E
dependence.
