Average (solid lines) and rms (shaded areas) of φ_p(10 − 100   GeV) (upper panel), TS (middle panel), and the scaling h(θ_s) (lower panel) as function of the intrinsic angular extent θ_s. For each θ_s, a sample of 500 simulations of the 1FGL J0030.7+0724 photon distribution between 10 and 100 GeV assuming a DM subhalo intensity profile was analysed with the 1FGL point-source-analysis framework.
