Comparison of integral source flux measurements above 1 TeV as calculated with two different methods. The flux estimate from maps is the total source flux according to the morphology model fit, assuming a spectral index of Γ = 2.3 (the Flux_Map column in the catalog). The flux estimate from spectra is computed from the total source best-fit spectral model extracted using aperture photometry and aperture correction (the Flux_Spec_Int_1TeV column in the catalog). The gray band in the background illustrates a systematic uncertainty of 30% on the flux values.
