Fig. 16


log    N(>S) − log    S curves in the soft band (0.5–2 keV, left panel) and the hard band (2–12 keV, right panel) for all detected X-ray sources (grey), identified active coronae with Pid > 90% (solid red lines) and unidentified plus extragalactic sources (solid blue blue). Sources either identified as active stars or with Pid > 90% are shown with red dotted lines, and sources either identified as extragalactic or unidentified sources with no infrared and no optical counterpart are shown with blue dotted lines. We show the expected contribution of extragalactic sources from Campana et al. (2001) plus Hasinger et al. (1998) in the soft band and from Mateos et al. (2008) and Campana et al. (2001) in the hard band. For the lower Galactic latitudes and in the hard band we compare our results with those of Ebisawa et al. (2001) (brown line) and Hands et al. (2004) (green line).
