Ratio of γ-ray spectra detected by Fermi LAT from different clouds to the calculated γ-ray spectrum if the CR proton flux in the clouds are similar to the local CR spectrum measured by PAMELA. The grey lines indicate the allowed range of variations related to uncertainties of the clouds’ total masses.
