Extended Data Fig. 1: Time-averaged broadband spectrum of 4FGL J1410.4+2820.

The two arrows represent the 3σ upper limits for the BL Lac flux obtained using one month of observation by Fermi/LAT before and after the GRB (in yellow and purple, respectively). The green band in the GeV energies represents the time-averaged GeV emission from 12 years of observation55. The emission from the blazar is at least two orders of magnitude weaker than the emission from the GRB.
