Fig. 1
Distribution of Log(νpeakfνpeak) synchrotron peak flux with indigo bars that represent the γ-ray subsample of 439 2WHSP-FGL sources, and light red-bars representing the 1255 γ-ray undetected 2WHSPs. The intersection between detected and undetected distributions suggests there may be numerous 2WHSP sources close to the detection threshold from Fermi-LAT. The 2WHSP catalog lists Log(νpeakfνpeak) values in 0.1 steps, and histogram-bins are centered on those values.
