XSvgadem

class sherpa.astro.xspec.XSvgadem(name='vgadem')

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC gadem model: plasma emission, multi-temperature with gaussian distribution of emission measure.

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. See the XSapec documentation for settings relevant to the APEC model (i.e. when switch=2).

Tmean

The mean temperature for the gaussian emission measure distribution, in keV.

Tsigma

The sigma of the temperature distribution for the gaussian emission measure, in keV.

nH

H density, in cm^-3.

He, C, N, O, Ne, Na, Mg, Al, Si, S, Ar, Ca, Fe, Ni

The abundance of the element in solar units.

Redshift

The redshift of the plasma.

switch

If 0, the mekal code is run to evaluate the model; if 1 then interpolation of the mekal data is used; if 2 then interpolation of APEC data is used. See [1] for more details. This parameter can not be thawed.

norm

The normalization of the model.
