Sbarufatti (INAF-OAB/PSU),\nM. Stamatikos (OSU), T. N. Ukwatta (LANL)\n(i.e. the Swift-BAT team):\n\nUsing the data set from T-327 to T+1275 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 170526A (trigger #754549)\n(Sbarufatti et al., GCN Circ. 21149).  The BAT ground-calculated position is\nRA, Dec = 4.723, 1.277 deg which is\n  RA(J2000)  =  00h 18m 53.6s\n  Dec(J2000) = +01d 16' 35.7\"\nwith an uncertainty of 2.4 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 94%.\n\nThe mask-weighted light curve shows a weak pulse structure that starts\nat ~T0, peaks at ~ T+1 s, and ends at ~ T+10 s. T90 (15-350 keV) is 7.9 +- 1.6 sec\n(estimated error including systematics).\n\nThe time-averaged spectrum from T+1.1 to T+10.0 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.25 +- 0.42.  The fluence in the 15-150 keV band is 1.6 +- 0.4 x 10^-7 erg/cm2.\nThe 1-sec peak photon flux measured from T+1.10 sec in the 15-150 keV band\nis 0.3 +- 0.2 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/754549/BA/",
