HGPS point-source sensitivity map and profile along the Galactic plane at a Galactic latitude b = 0°. The sensitivity is given in % Crab, for a correlation radius Rc = 0.1°, assuming a spectral index Γ = 2.3. This sensitivity is computed under the isolated point source assumption and is thus better than the actual sensitivity achieved for the HGPS source catalog (see Sect. 4.12).
