Diagram of the upper limits on the gamma-ray energy flux as a function of radio energy fluxes (νFν). The FRB events reported are those with available information on their radio flux density and with a correctly estimated gamma-ray flux UL (i.e. sufficient gamma-ray exposure). Gamma-ray upper limits from the analysis on 10 s (10 000 s) are plotted in blue (red). To avoid further confusion we plot only the δ_T = 10 and 10 000 s results, the results on δ_T = 100 and 1000 s provide UL in between the two extreme time windows (10 and 10 000 s). FRB sources with known host-galaxy are highlighted with a black outline.
