XSrefsch

class sherpa.astro.xspec.XSrefsch(name='refsch')[source]

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC refsch model: reflected power law from ionized accretion disk.

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 between 0 and 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.

T_disk

The disk temperature in K.

xi

The disk ionization parameter: see [1] for more details.

Betor10

The power law dependence of emissivity: see [1] for more details.

Rin

The inner radius, in units of GM^2/c.

Rout

The outer radius, in units of GM^2/c.

accuracy

The internal model accuracy: points of spectrum per energy decade.

norm

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

Methods Documentation

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.

regrid(*arrays)
reset()
set_center(*args, **kwargs)
startup()

Called before a model may be evaluated multiple times.
