XSvvapec

class sherpa.astro.xspec.XSvvapec(name='vvapec')[source]

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC vvapec model: APEC emission spectrum.

The model is described at [1], with XSapec describing how it is implemented in Sherpa.

kT

The temperature of the plasma, in keV.

H, He, Li, Be, B, C, N, O, F, Ne, Na, Mg, Al, Si, P, S, Cl, Ar,
K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn

The abundance of the element in solar units.

Redshift

The redshift of the plasma.

norm
