XScompbb

class sherpa.astro.xspec.XScompbb(name='compbb')[source]

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC compbb model: Comptonization, black body.

The model is described at [1].

kT

The blackbody temperature, in keV.

kTe

The electron temperature of the hot plasma, in keV.

tau

The optical depth of the plasma.

norm

The model normalization: it is the same definition as used for the XSbbodyrad model.

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.
