Sakamoto (AGU), M. Stamatikos (OSU), T. N. Ukwatta (LANL) (i.e. the Swift-BAT team): Using the data set from T-239 to T+667 sec from the recent telemetry downlink, we report further analysis of BAT GRB 180728***A*** (trigger #850471) (NAME, et al., GCN Circ. xxxx). The BAT ground-calculated position is RA, Dec = 253.574, -54.037 deg which is RA(J2000) = 16h 54m 17.7s Dec(J2000) = -54d 02' 13.7" with an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment). The partial coding was 57%. [Description about the mask-weighted light curve] T90 (15-350 keV) is 8.7 +- 0.3 sec (estimated error including systematics). The time-averaged spectrum from T-0.2 to T+36.5 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.97 +- 0.03. The fluence in the 15-150 keV band is 3.0 +- 0.0 x 10^-05 erg/cm2. The 1-sec peak photon flux measured from T+12.61 sec in the 15-150 keV band is 132.0 +- 2.9 ph/cm2/sec. All the quoted errors are at the 90% confidence level. The results of the batgrbproduct analysis are available at http://gcn.gsfc.nasa.gov/notices_s/850471/BA/
