XShrefl

class sherpa.astro.xspec.XShrefl(name='hrefl')

Bases: sherpa.astro.xspec.XSMultiplicativeModel

The XSPEC hrefl model: reflection model.

The model is described at [1].

thetamin

The minimum angle, in degrees, between source photons incident on the slab and the slab normal.

thetamax

The maximum angle, in degrees, between source photons incident on the slab and the slab normal.

thetamobs

The angle, in degrees, between the observer’s line of sight and the slab normal.

Feabun

The iron abundance relative to solar.

FeKedge

The iron K edge energy, in keV.

Escfrac

The fraction of the direct flux seen by the observer: see [1] for more details.

covfac

The normalization of the reflected continuum: see [1] for more details.

redshift

The redshift.

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.
