XSpexmon

class sherpa.astro.xspec.XSpexmon(name='pexmon')

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC pexmon model: neutral Compton reflection with self-consistent Fe and Ni lines.

The model is described at [1].

PhoIndex

The 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 of 1 for an isotropic source above the disk, less than 0 for no direct 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.

Incl

The inclination angle in degrees.

norm

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

apply(outer, *otherargs, **otherkwargs)

calc(pars, xlo, *args, **kwargs)

get_center()

guess(dep, *args, **kwargs)

Set an initial guess for the parameter values.

Attempt to set the parameter values, and ranges, for the model to match the data values. This is intended as a rough guess, so it is expected that the model is only evaluated a small number of times, if at all.

reset()

set_center(*args, **kwargs)

startup()

Called before a model may be evaluated multiple times.
