In particular, we include the astrophysical uncertainties from the dark matter distribution and allow for unspecified additional dark matter components. We demonstrate through a detailed numerical fit that the strength and shape of the $\\gamma$-ray spectrum can indeed be described by the model in various regions of dark matter masses and couplings.
