Reconstructed energy spectra of selected PS pixels based on model Ml. The pixels were selected by sorting them by their geometric mean flux in the 1.00–1.77 GeV (red, down-pointing triangles) and 100–177 GeV energy bins (blue, up-pointing triangles) and then choosing the brightest, 10th, 100th, and 1000th brightest source in each of the two energy bins. Right: positions of the selected PSs. Left: corresponding energy spectra, matched by color. The triangle markers display the posterior geometric mean flux reconstructed for the sources in each energy bin, while the thin continuous lines show the posterior spectrum samples associated with sources. The spectra are plotted on log-log scale.
