Fraction of FSRQs (FSRQ / (FSRQ + BLL)) plotted against the energy range for each catalog. Clearly, the softer gamma-ray catalogs detect a higher fraction of FSRQs, with the 2FLE reporting the highest fraction out of the 2FLE, 4FGL-DR4, 2FHL, and the 3FHL. This indicates that most FSRQ peak emission occurs in the MeV, while generally, BLLs peak at GeV and TeV energies
