Left: Inferred intrinsic local sGRB rate R_sGRB for all the BNS population models that allow physical jet fractions (with median f_j ≤ 1), under the assumption of a universal structured jet. Right: Comparison of the inferred f_j posterior distributions for the fiducial BNS population across the four analysed jet structures: universal structured, universal top-hat, non-universal flat, and non-universal log-normal.
