Fig. 2


HGPS minimum safe energy threshold as a function of Galactic longitude for a latitude of b = 0°. The blue curve shows the minimum threshold for hard cuts (used for maps), and the green curve indicates standard cuts (used for spectra). The black dots represent the safe threshold for each observation run obtained for the hard cuts configuration. The few black dots below the blue line correspond to runs at Galactic latitude |b| > 2°.
