XSdisk
(name='disk')[source]¶ Bases:
sherpa.astro.xspec.XSAdditiveModel
The XSPEC disk model: accretion disk, black body.
The model is described at [1].
Note
Deprecated in Sherpa 4.10.0
The
NSmass
parameter has been renamed toCenMass
to match the XSPEC definition. The nameNSmass
can still be used to access the parameter, but this name will be removed in a future release.-
accrate
¶ The accretion rate, in Eddington luminosities.
-
CenMass
¶ The central mass, in solar mass units.
-
Rinn
¶ The inner disk radius in gravitational units (three Schwarzschild radii).

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.
