Red data points: rest-frame 0.1−100 GeV luminosity light curve of GRB 190114C during and after UPE phase obtained from Fermi-LAT. Green dashed line: best fit for power-law behavior of the luminosity following the UPE phase with slope of 1.2 ± 0.04 and amplitude of 7.75 ± 0.44 × 10⁵² erg s⁻¹. Black data points: rest-frame 0.3−10 keV luminosity expressed in the rest frame obtained from Swift-XRT. It follows a power-law behavior with an amplitude of A_X = (5.14 ± 2.03) × 10⁵² erg s⁻¹ and a slope of α_X = 1.37 ± 0.05.
