XSzvfeabs

class sherpa.astro.xspec.XSzvfeabs(name='zvfeabs')

Bases: sherpa.astro.xspec.XSMultiplicativeModel

The XSPEC zvfeabs model: photoelectric absorption with free Fe edge energy.

The model is described at [1].

nH

The equivalent hydrogen column (in units of 10^22 atoms/cm^2).

metals

The abundance relative to solar.

FEabun

The iron abundance relative to solar.

FEKedge

The Fe K edge energy, in keV.

redshift

The redshift of the absorber.

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.
