XScemekl

class sherpa.astro.xspec.XScemekl(name='cemekl')[source] [edit on github]

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC cemekl model: plasma emission, multi-temperature using mekal.

The model is described at [1].

alpha

The power-law index of the emissivity function.

Tmax

The maxmimum temperature, in keV.

nH

H density, in cm^-3.

abundanc

The abundance relative to Solar, as set by set_xsabund.

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.

get_center() [edit on github]
guess(dep, *args, **kwargs) [edit on github]

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.

regrid(*arrays) [edit on github]
reset() [edit on github]
set_center(*args, **kwargs) [edit on github]
startup(cache) [edit on github]

Called before a model may be evaluated multiple times.
