|AHELP for CIAO 4.3 Sherpa v1||
Redshifted photoelectric absorption with low energy window. XSpec model.
A redshifted photoelectric absorption using Balucinska-Church and McCammon (ApJ 400, 699) cross-sections. The relative abundances are set by the set_xsabund command.
M(E) = exp(-nH*sigma(E*(1+z))) for E <= windowe
M(E) = 1 for E > windowe
where sigma(E) is the photo-electric cross-section, NOT including Thomson scattering.
This is a multiplicative model component.
|1||nh||equivalent hydrogen column (in units of 10^22 atoms/cm^2)|
|2||windowe||window energy (keV)|
