Scatter plot of FWHM_min and T₉₀ for the Fermi/GBM sample along with the corresponding marginal distributions. Blue (red) points represent short (long) GRBs. Gold points represent SN-associated GRBs. Magenta, lime, and cyan points represent SEE-GRBs from Lien et al. (2016), Lan et al. (2020), Kaneko et al. (2015), respectively. Three extragalactic MGFs candidates, 180128A, 200415A, and 231115A, are shown in brown. The SEE-GRBs from the three samples considered are shown altogether in grey in the top and right panel. We also show with a black star the two peculiar LGRBs, 211211A and 230307A, associated with a kilonova event and 191019A, which may be a short GRB that exploded in a dense environment. We also highlight the peculiar short collapsar GRB 200826A associated with an SN.
