AHELP for CIAO 4.6 Sherpa v2


Context: models


Redshifted photoelectric absorption with variable abundances. XSpec model.


Photoelectric absorption with variable abundances using cross-sections set by the set_xsxsect command. The column for each element is in units of the column in a solar abundance column of an equivalent hydrogen column density of 10^22 cm^2. The Solar abundance table used is set by the set_xsabund command. This model is identical to xszvphabs except for the way that the parameters are defined.

This is a multiplicative model component.
