RA(J2000) = 16h 45m 05s Dec(J2000) = +13d 49' 49"with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a single-peak with substructure with a duration of about 35 sec. The peak count rate was ~2000 counts/sec (15-350 keV), at ~10 sec after the trigger. This was an image trigger, but with a clear light curve.
RA(J2000) = 16h 45m 04.3s Dec(J2000) = 13d 49' 31.4"with an uncertainty of 4.6 arcseconds (radius, 90% containment). This location is 18.1 arcseconds from the BAT on-board position, within the BAT error circle.
RA(J2000) = 16:45:04.01
DEC(J2000) = +13:49:36.1
with a 1-sigma error radius of about 0.6 arc sec. This position
is 6.3 arcseconds from the center of the XRT error circle. The
estimated magnitude is 18.0 in white and 17.6 in v with
1-sigma errors of about 0.5 mag. The positions agree in both
white and v. No correction has been made for the expected
extinction corresponding to E(B-V) of 0.08.
RA (J2000): 16h 45m 4.06s Dec (J2000): +13d 49' 35.6"with an uncertainty of 2.5 arcsec (radius, 90% confidence).
