Comparison of the spectra of the sources from Table 1 in the 1−300 GeV band, obtained with a standard Fermi analysis procedure (red circles represent the flux measurements, red arrows – upper limits), and the estimated source fluxes in the 100 − 300 GeV band, obtained using aperture photometry technique (blue triangles). Aperture photometry data points in the 100 − 300 GeV band are artificially shifted to slightly higher energy to ensure that they are visible, and displayed with the measurements from the likelihood analysis in the same energy band.
