Collection of six observer-frame GRBs with medium to high luminosity and low variability. Each panel reports the GRB name along with the (V_f, log L_iso) pair. All of them are BAT bursts (15–150 keV), except for BeppoSAX GRB 000210 (40–700 keV) in the bottom right panel. In the case of BAT LCs, the count rates are expressed in count s⁻¹ per fully illuminated detector for an equivalent on-axis source.
