Table 1: Data on the light curves for GRBs with known redshifts used in this analysis. The third column gives the time lags between the arrivals of every identical genuine variation points in the third (high-energy) spectral band and the first (low-energy) one. For every light curve, we give the weighted means of the time lags in 64 ms BATSE domain, combining the genuine variation points for that GRB. Both statistical and systematic errors are included. The average spread of individual time lags is below the mesurement uncertainty. Also indicated are the results obtained by combining OSSE 64 ms light curves in the 3-6 MeV energy range with BATSE light curves in the 115-320 keV energy band. In the case of GRB 980329, the results of BATSE 64 ms and TTE 2.7 ms resolution measurements are combined with the OSSE-BATSE 64 ms comparisons.
