|AHELP for CIAO 4.3 Sherpa v1||
Photo-electric absorption. XSpec model.
Photoelectric absorption using cross-sections set by the set_xsxsect command. The relative abundances are set by the set_xsabund command.
M(E) = exp(-nH*sigma(E))
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)|
