TITLE: GCN CIRCULAR NUMBER: 15010 SUBJECT: GRB 130716A Swift-BAT Spectral lag analysis DATE: 13/07/18 15:11:29 GMT FROM: Takanori Sakamoto at AGU J. Norris (BSU), S. D. Barthelmy (GSFC), T. Sakamoto (AGU), N. Gehrels (GSFC) We report the spectral lag analysis for GRB 130716A (GCN Circ. 15506) based on the BAT data. Using 16-ms binned light curve, the spectral lag for the 25-50 keV to 100-350 keV bands is -2 (+50/-40) ms, and +11 (+25/-14) ms for the 15-25 keV to 50-100 keV bands. Although the lag value is not well constrained (relatively large errors), we believe this burst is more consistent with short burst category. There is no evidence for extended emission.
