Markwardt (GSFC),\nD. M. Palmer (LANL), T. Sakamoto (AGU),\nM. Stamatikos (OSU), J. Tueller (GSFC),\n(i.e. the Swift-BAT team):\n\nUsing the data set from T-120 to T+1190 sec from the\nrecent telemetry downlink, we report further analysis of\nBAT GRB GRB 150203A (trigger #629578) (Ukwatta, et al.,\nGCN Circ. 17377).The BAT ground-calculated position is\nRA, Dec = 98.394, 6.952 deg which is\n   RA(J2000)  =  06h 33m 34.5s\n   Dec(J2000) = +06d 57' 07.1\"\nwith an uncertainty of 1.1 arcmin, (radius, sys+stat,\n90% containment). The partial coding was 84%.\n\nBAT light curve shows a single multi-peaked episode starting\naround T-2 sec, and ending around T+32 sec. The two main\npeaks of the light curve can be seen at T+1 sec and T+18 sec.\nT90 (15-350 keV) is 25.8 +- 5.0 sec (estimated error\nincluding systematics).\n\nThe time-averaged spectrum from T-0.8 to T+32.3 sec\nis best fit by a simple power-law model.  The power law\nindex of the time-averaged spectrum is 1.90 +- 0.12.\nThe fluence in the 15-150 keV band is 9.1 +- 0.6 x 10^-07\nerg/cm2. The 1-sec peak photon flux measured from T+16.79\nsec in the 15-150 keV band is 0.9 +- 0.1 ph/cm2/sec.\nAll the quoted errors are at the 90% confidence level.\n\nThe results of the batgrbproduct analysis are available at\nhttp://gcn.gsfc.nasa.gov/notices_s/629578/BA/",
