Luminosity probability distributions obtained considering either a power-law or a log-normal DTD (left and right panel, respectively). Results obtained with the broken power-law model are shown in red, and the ones obtained with the structured jet model are in blue. The shaded areas represent the 90% credible intervals. Luminosity functions from W15 are also shown in yellow. The measured luminosity for GRB 170817A is shown in grey as a reference point.
