Comparison of the second Fermi LAT source catalog (Nolan et al. 2012) and candidates from the reconstruction for which an association in the second Fermi LAT catalog has been found. Panel a) shows the histogram and scatter plot of the spectral indices γ^(u) of candidates versus catalog sources. In the latter, a 1:1 line (black solid) is plotted for comparison, and the markers indicate the fit spectral shape, cf. legend. Panel b) shows the histogram and scatter plot of the logarithmic total fluxes log ₁₀(F/F₀), where F₀ = 1 cm^-2 s^-1. The scatter plot contains a 1:1 line (black solid) for comparison.
