Parsotan (GSFC/UMBC), M. Stamatikos (OSU)\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-36 to T+963 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 231210B (trigger #1201696)\n(Page, et al., GCN Circ. 35314).  The BAT ground-calculated position is\nRA, Dec = 95.803, -48.335 deg which is\n   RA(J2000)  =  06h 23m 12.7s\n   Dec(J2000) = -48d 20' 04.6\"\nwith an uncertainty of 1.8 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 17%.\n \nThe mask-weighted light curve shows a FRED pulse potentially followed by a dimmer spike.\nT90 (15-350 keV) is 7.47 +- 0.65 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T-0.23 to T+7.82 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.08 +- 0.19.  The fluence in the 15-150 keV band is 1.4 +- 0.2 x 10^-06 erg/cm2.\nThe 1-sec peak photon flux measured from T-0.24 sec in the 15-150 keV band\nis 3.9 +- 0.7 ph/cm2/sec.  All the quoted errors are at the 90% confidence\nlevel.\n \nThe results of the batgrbproduct analysis are available at\nhttp://gcn.gsfc.nasa.gov/notices_s/1201696/BA/",
