XSpexrav

class sherpa.astro.xspec.XSpexrav(name='pexrav')

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC pexrav model: reflected powerlaw, neutral medium.

The model is described at [1].

PhoIndex

The first power-law photon index.

foldE

The cut-off energy (E_c) in keV. Set to 0 for no cut off.

rel_refl

The reflection scaling parameter (a value between 0 and 1 for an isotropic source above the disk, less than 0 for no reflected component).

redshift

The redshift of the source.

abund

The abundance of the elements heaver than He relative to their solar abundance, as set by the set_xsabund function.

Fe_abund

The iron abundance relative to the solar abundance, as set by the set_xsabund function.

cosIncl

The cosine of the inclination angle in degrees.

norm

The normalization of the model: see [1] for an explanation of the units.

XSpexriv, XSpexmon

Notes

The precision of the numerical integration can be changed by using the set_xsxset function to set the value of the PEXRAV_PRECISION keyword, which defines the fractional precision. The default is 0.01 (1%).
