XSgrbm

class sherpa.astro.xspec.XSgrbm(name='grbm')[source]

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC grbm model: gamma-ray burst continuum.

The model is described at [1].

Note

Deprecated in Sherpa 4.10.0

The temp parameter has been renamed tem to match the XSPEC definition. The name temp can still be used to access the parameter, but this name will be removed in a future release.

alpha

The first powerlaw index.

beta

The second powerlaw index.

tem

The characteristic energy, in keV.

norm

The normalization of the 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.
