Figure 3: (a) The variabilities and peak luminosities of the data set, excluding GRB980425. In this case, indicates the variabilities for the 45% smoothing timescale of the light curve. The solid and dotted lines are the best-fit line and deviation, respectively, in plane. (Figure after Reichart et al. [102]; see Figure therein. @ AAS. Reproduced with permission.) (b) The plane for the sample of 32 GRBs with measured redshift. The best-fit lines and deviations are also displayed: solid lines are computed with the Reichart et al. [102] method, dashed-dotted lines with the D'Agostini [153] method, and the dashed lines are recovered by Guidorzi et al. [149]. (Figure after Guidorzi et al. [151]; see Figure therein.) (c) relation for the set of 551 BATSE GRBs. The best-fit lines and regions are also shown, the solid lines are fitted with the Reichart et al. [102] method, the dashed-dotted lines with the D'Agostini [153] method, and the dashed lines are recovered by Guidorzi et al. [149]. (Figure after Guidorzi et al. [151]; see Figure therein.)
