XSsnapec

class sherpa.astro.xspec.XSsnapec(name='snapec')

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC snapec model: galaxy cluster spectrum using SN yields.

The model is described at [1]. The set_xsxset and get_xsxset functions are used to set and query the XSPEC XSET parameters to control the APEC model.

kT

The temperature of the plasma, in keV.

N_SNe

The number of SNe (in units of 10^9).

R

The percentage of SN1a.

SNIModelIndex

SNIa yield model: see [1] for more details.

SNIIModelIndex

SNIIa yield model: see [1] for more details.

redshift

The redshift of the plasma.

norm

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