Gamma-Ray Burst Prompt Correlations

(a) versus distribution for six GRBs with measured redshifts. The dashed line represents the power law fit to the lag times for ranges consisting of count rates larger than intensity (squares), yielding . The lag time is computed using channel 1 and channel 3 of the BATSE instrument. (Figure after Norris et al. [113]; see Figure therein. @ AAS. Reproduced with permission.) (b) The distribution in the versus plane. The correlation coefficient is , . The solid line represents the best-fit line and two dashed lines delineate deviation. (Figure after Tsutsui et al.
