XSdust
(name='dust')[source]¶ Bases:
sherpa.astro.xspec.XSMultiplicativeModel
The XSPEC dust model: dust scattering.
The model is described at [1].
-
Frac
¶ The scattering fraction at 1 keV.
-
Halosz

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.
