GRB 181003***A***, Swift-BAT refined analysis S. D. Barthelmy (GSFC), J. R. Cummings (CPI), H. A. Krimm (NSF/USRA), A. Y. Lien (GSFC/UMBC), C. B. Markwardt (GSFC), D. M. Palmer (LANL), T. Sakamoto (AGU), M. Stamatikos (OSU), T. N. Ukwatta (LANL) (i.e. the Swift-BAT team): Using the data set from T-240 to T+962 sec from the recent telemetry downlink, we report further analysis of BAT GRB 181003***A*** (trigger #865179) (NAME, et al., GCN Circ. xxxx). The BAT ground-calculated position is RA, Dec = 52.482, -33.991 deg which is RA(J2000) = 03h 29m 55.6s Dec(J2000) = -33d 59' 26.7" with an uncertainty of 1.7 arcmin, (radius, sys+stat, 90% containment). The partial coding was 96%. [Description about the mask-weighted light curve] T90 (15-350 keV) is 25.5 +- 4.8 sec (estimated error including systematics). The time-averaged spectrum from T-11.2 to T+18.0 sec is best fit by a power law with an exponential cutoff. This fit gives a photon index -0.18 +- 1.10, and Epeak of 56.2 +- 14.2 keV (chi squared 47.70 for 56 d.o.f.). For this model the total fluence in the 15-150 keV band is 4.3 +- 0.7 x 10^-07 erg/cm2 and the 1-sec peak flux measured from T+1.86 sec in the 15-150 keV band is 0.6 +- 0.1 ph/cm2/sec. A fit to a simple power law gives a photon index of 1.55 +- 0.19 (chi squared 58.61 for 57 d.o.f.). All the quoted errors are at the 90% confidence level.
