Description

Following the feature #1520, from Nathan, (GModels for Dark Matter Halo Density Profiles). I would suggest to add the gamma ray spectra for dark matter, because it is not easy to model with the current functions used in gammalib.

I would like to suggest the solution adopted by the Fermi collaboration in their science tools. They use the DMFit tool to calculated the gamma spectrum, then from a xml file they just model the spectrum using 4 parameters, normalization, channel, branching ratio and mass.

From M.Cirelli et al I have used their Mathematica notebook to create the ASCII file for different wimp mass and annihilation channels for the CTA energy range.

Cheers,
Gonzalo.
