The BAT ground-calculated position is\nRA, Dec = 99.479, 23.982 deg which is \n   RA(J2000)  =  06h 37m 55.0s \n   Dec(J2000) = +23d 58' 56.0\" \nwith an uncertainty of 2.6 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 59%.\n \nThe mask-weighted light curve shows a roughly symmetric peak starting\nat ~T+0, peaking at ~T+23, and ending at ~T+50 sec.\nT90 (15-350 keV) is 24 +- 4 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T+5.0 to T+34.5 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.92 +- 0.35.  The fluence in the 15-150 keV band is 3.2 +- 0.7 x 10^-7 erg/cm2.\nThe 1-sec peak photon flux measured from T+25.35 sec in the 15-150 keV band\nis 0.1 +- 0.1 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/306793/BA/",
