zxipcf: partial covering absorption by partially ionized material
This model uses a grid of XSTAR photionized absorption models (calculated
assuming a microturbulent velocity of 200km/s) for the absorption, then
assumes that this only covers some fraction f of the source, while the
remaining (1f) of the spectrum is seen directly. This is the model used
by Reeves et al. (2008)
'On why the iron Kshell absorption in AGN is not
the signature of the local warmhot intergalactic medium', and may also be
more generally applicable to the spectral complexity seen in Narrow Line
Seyfert 1 AGN (Miller et al. 2007).
