XSc6pvmkl

class sherpa.astro.xspec.XSc6pvmkl(name='c6pvmkl')

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC c6pvmkl model: differential emission measure using Chebyshev representations with multi-temperature mekal.

The model is described at [1]. It differs from XSc6vmekl by by using the exponential of the 6th order Chebyshev polynomial.

CPcoef1, CPcoef2, CPcoef3, CPcoef4, CPcoef5, CPcoef6

Chebyshev polynomial coefficients.

nH

H density, in cm^-3.

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

The abundance relative to Solar.

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.
