XSbmc

class sherpa.astro.xspec.XSbmc(name='bmc')

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC bmc model: Comptonization by relativistic matter.

The model is described at [1].

Note

Deprecated in Sherpa 4.10.0

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

kT

The temperature of the thermal photon source in keV.

alpha

The energy spectral index.

log_A

The log of the A parameter: see [1] for more details.

norm

The normalization of the model: see [1] for an explanation of the units.

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.

teardown()
