Using 2-ms binned light curves, the spectral lag\nfor the 15-25 keV to 50-100 keV bands is 0.6 +-0.7 ms, and -2.5 +-0.7 mc\nfor the 25-50 keV to 100-350 keV bands for both peaks combined.\nThese lag values and the hard spectrum (GCN Circ. 14741) place\nthis burst in the short burst category.  There is no evidence\nfor extended emission at the 0.005 cnts/det/sec level.",
