FERMI-LAT-SCIENTIFIC PLOTS
8
Histograms demonstrating the calculation of the R iso, sky (E, L) function. Top left: amount of time Fermi spent while at each L bin; top
right: number of events in the
θ< 50◦subset of the isotropic-component data set detected while Fermi was inside each of the L bins; bottom: ratio
of these two histograms showing the detection rate of such events while at some
L bin. We fit the rate histogram with a fifth degree polynomial,
shown with the black curve. The histograms shown here correspond to log-energy bin #1 (energy≃100 MeV).
