S. D. Barthelmy (GSFC), J. Norris (BSU) for the BAT Team:
We report the spectral lag analysis for GRB 111210A (GCN Circ. 12632 & 12640)
based on the BAT data. Using 16-ms binned light curves, the spectral lag
for the 15-25 keV to 50-100 keV bands is 38 +26/-33 msec, and 36 +16/-18 msec
for the 25-50 keV to 100-350 keV bands for both peaks combined. For just
the second peak, the lag for 15-25 keV to 50-100 keV bands is 97 +52/-40 msec.
These lag values place this burst in the long burst category.
