M. Palmer (LANL), M. Stamatikos (OSU),\nT. N. Ukwatta (LANL) (i.e. the Swift-BAT team):\n\nUsing the data set from T-60 to T+243 sec from the recent telemetry\ndownlink,\nwe report further analysis of BAT GRB 200701A (trigger #980421)\n(Bernardini et al., GCN Circ. 28052).  The BAT ground-calculated position is\nRA, Dec = 123.563, -14.553 deg which is\n   RA(J2000)  =  08h 14m 15.2s\n   Dec(J2000) = -14d 33' 09.8\"\nwith an uncertainty of 1.7 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 77%.\n\nThe mask-weighted light curve shows a single-pulse structure that\nstarts at ~T-7 s and peaks at ~T0. The main pulse ends at ~T+20 s,\nfollowed by a weak tail that lasts till ~T+40 s. T90 (15-350 keV)\nis 38.9 +- 8.6 sec (estimated error including systematics).\n\nThe time-averaged spectrum from T-6.81 to T+42.17 sec is best fit\nby a simple power-law model.  The power law index of the time-averaged\nspectrum is 1.91 +- 0.16.  The fluence in the 15-150 keV band\nis 9.3 +- 1.0 x 10^-7 erg/cm2. The 1-sec peak photon flux measured\nfrom T-1.72 sec in the 15-150 keV band is 0.7 +- 0.2 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/980421/BA/",
