XSplcabs

class sherpa.astro.xspec.XSplcabs(name='plcabs')[source]

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC plcabs model: powerlaw observed through dense, cold matter.

The model is described at [1].

nH

The column density, in units of 10^22 cm^-2.

nmax

The maximum number of scatterings. This parameter can not be thawed.

FeAbun

The iron abundance.

FeKedge

The energy of the Fe K edge, in keV.

PhoIndex

The power law photon index.

HighECut

The high-energy cut-off threshold energy, in keV.

foldE

The high-energy cut-off e-folding energy, in keV.

acrit

The critical albedo for switching to elastic scattering. See [1] for more details.

FAST

If set to a value above 1, use a mean energy shift instead of integration. This parameter can not be thawed.

redshift

The redshift of the source.

norm

The normalization of the model.
