Example of validation plots for the FSRQ 4C +28.07. The top panels show the case for which the spectral index (α for this source) is fixed. In all plots we are considering the 0.1–100 GeV energy range. The bottom panels show the case for which the spectral index is free to vary. The ratio of the flux to the flux uncertainty (left panels) is expected to be approximately proportional to the square root of TS. The middle panels show the distributions of the flux statistical uncertainties. Flux distributions are shown in the right panels. In this example, the distributions are good except for the outliers highlighted within green squares, which should be either further investigated or removed. In the histograms, the dashed lines represent the results from all time bins. The solid lines represent bins that did not converge. Notice that outliers are not necessarily the results from analyses that did not converge.
