a) Total energy of the X-ray light curve E_x vs. prompt emission energy E_iso. The black line marks the condition E_x = E_iso. b) Total energy of the Type 0 light curves E_PL vs. E_iso. c) Total energy of the first, shallow segment of Type Ia light curves E_shallow vs. E_iso. The red line is the best-fit of the golden sample data: Log [E_shallow]  = (20 ± 85) + (0.6 ± 1.6)Log [E_iso] . d) Total energy of the steep decay of Type Ib and II light curves E_steep vs. E_iso. e) Total energy of the plateau of Type II light curves E_plateau vs. E_iso. The blue line is the best fit of the complete sample data: Log [E_plateau]  = (5.8 ± 1.4) + (0.85 ± 0.03)Log [E_iso] . f) Total energy of the final normal decay of Type Ia and Type II light curves E_norm vs. E_iso. The grey dots refer to the fluence-fluence plot of the 278 long GRB light curves with (stars) and without (squares) flares from the XRT Catalogue by Margutti et al. (in prep.).
