Spectra of the four molecular clouds as derived from the Fermi-LAT analysis. For comparison, the spectrum derived for η Car is also shown in grey. Additionally, a model derived from an injected CR spectrum is shown. The CR spectrum was modelled as a power law with an index of 2.0 and an exponential cut-off at 2 TeV. The normalisation was scaled arbitrarily.
