XRT position for GRB 110715A enhanced by UVOT field astrometry

Data were analysed using HEASOFT version 6.35.2


RA (J2000):	15h 50m 44.04s (237.68348)
Dec (J2000):	-46° 14′ 06.7′′ (-46.23520)
90% Error radius:	1.4′′
Number of overlaps included in position:	30
Exposure time in final position:	15279 s

Total number of overlaps considered:	40
Total overlap time:	16356 s
Number of overlaps where no X-ray source was found:	8
Number of low-X-ray-count fits rejected:	0
Number of spurious fits rejected:	0
Number of bad astrometric corrections:	0
Number of outliers removed:	2

For details of how these positions are produced, and why some positions are rejected, see the online documentation.
