XSapec

class sherpa.astro.xspec.XSapec(name='apec')

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC apec model: APEC emission spectrum.

The model is described at [1]. The set_xsabund and get_xsabund functions change and return the current settings for the relative abundances of the metals. The set_xsxset and get_xsxset functions are used to set and query the XSPEC XSET parameters, in particular the keywords “APECROOT”, “APECTHERMAL”, “APECVELOCITY”, and “APEC_TRACE_ABUND”.

kT

The temperature of the plasma, in keV.

Abundanc

The metal abundance of the plasma, as defined by the set_xsabund function and the “APEC_TRACE_ABUND” xset keyword.

redshift

The redshift of the plasma.

norm

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