Cumulative distributions of the photon peak flux (in the energy range 10–1000 keV) for the GRBs detected by HERMES HP (left panel), Constellation A (center), and Constellation B (right). In each panel, the cumulative curve for long (short) GRBs is shown in green (blue), and the shaded region includes 68% of the realisations. Orange (gray) dashed curves show the contribution of the S (X) detection mode. For Constellations A and B, almost all long GRBs are detected by the X mode, making the dashed gray curve almost overlap with the total distribution (solid green curve).
