Comparison of the HEGS catalogue results with results from the HEGS maps and results from earlier publications. Left: integral flux above 300 GeV obtained with the HEGS maps (with a spectral index fixed to 3) compared to the integral flux above 300 GeV determined in the dedicated analysis. The colour indicates the spectral index value obtained in the dedicated analysis. Right: integral flux above 300 GeV obtained with the HEGS analysis compared to the integral flux above 300 GeV provided in earlier publications (see list in Table 1), removing the sources found to be variable (see list in Table 6). The colour indicates the absolute difference in spectral index values from the HEGS catalogue and those from archival publications. The point on the right top corner of the left plot is PKS 2155-304 and has been marked for the reader as well as PKS 0548-322 on the right plot. The grey area represents the 20% systematic uncertainties estimated by H.E.S.S.
