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 ....
Model for partial covering of partially ionised absorbing material.
This model is now in the Xspec release and this page is superceded by the Xspec manual
This is a multiplicative model. The parameters are
par1 = column density in units of 1022 cm^-2
par2 = log(xi) where xi=L/nr^2
par3 = covering fraction f
par4 = redshift
To install this model download the source code (zxipcf.f), model datafile (zxipcf_mtable.fits), and the model parameter description file (zxipcf_lmodel.dat). zxipcf will look for its model datafile in the current directory or the directory specified in xspec by using xset ZXIPCF_DIR directory.
