Cumulative logN(>S) – log S distribution for the HGPS sources, showing the number of sources N above given flux thresholds S (integral flux above 1 TeV in % Crab). The line and error band show the result of an unbinned PL fit above a flux threshold of 10% Crab; the dashed line in the 1–10% Crab flux range illustrates the extension of the PL to fluxes below 10% Crab (for comparison, not fitted in that range).
