XSdisko

class sherpa.astro.xspec.XSdisko(name='disko')[source]

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC disko model: accretion disk, inner, radiation pressure viscosity.

The model is described at [1].

NSmass

The accretion rate, in Eddington luminosities.

NSmass

The central mass, in solar mass units.

Rinn

The inner disk radius in gravitational units (three Schwarzschild radii).

alpha

The viscosity.

norm

The normalization of the model: see [1] for details.

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.
