From top to bottom: Luminosity vs. time (the vertical green lines indicate t₀ (the central one), t₀ − 2τ_r (on the left), and t₀ + 2τ_d (on the right); the red line represents the fit function); Residuals vs. time; Photon index vs. time (the horizontal green lines show the best-fit value of Γ plus or minus its uncertainty; the horizontal red lines show the same but for Γ_4LAC); and the parameter values (see text) for one of the GRBBLs identified in 4FGL J0108.6+0134.
