Top: L₀ vs. T₀ for two separate groups: (i) L-GRBs (red circles, excluding the AG-rise cases), whose best-fit PL and 1σ uncertainty regions are shown by the solid red line and red-shaded area, respectively; (ii) S + SEE-GRBs (blue squares and cyan pentagons, respectively), whose best-fit PL is shown by the solid blue line within the blue-shaded area of the 1σ region. The L-GRBs of the AG-rise sample (green stars) were not used for the modelling. Also shown are the corresponding marginalised distributions. Bottom: L₀-T₀-E_γ, iso relation for the 180 GRBs with accurate measurements available, along with the best-fit model and 2σ uncertainty region.
