Systematic Spectral Lag Analysis of Swift Known- GRBs
The lag versus isotropic peak luminosity. The blue points are our results. The red points are the results which are reported in Ukwatta et al. 2010. The blue lines are best fit values of power-law fitting. The black dotted lines show the region corresponding to variance . (a) Between 100–200 keV and 25–50 keV and (b) between 100–200 keV and 50–100 keV.
