Upper panel: Fermi-LAT energy flux (blue) and photon flux (red) light curves obtained between 0.1 and 300 GeV. The solid black line represents the best-fit curve found using our model. Lower panel: all the photons with energies >100 MeV and probabilities >90% of being associated with GRB 190114C. Fermi-LAT data were reduced using the public database at the Fermi website.
