XRT position for GRB 180727A enhanced by UVOT field astrometry

Data were analysed using HEASOFT version 6.35.2


RA (J2000):	23h 06m 39.86s (346.66609)
Dec (J2000):	-63° 03′ 06.7′′ (-63.05186)
90% Error radius:	2.5′′
Number of overlaps included in position:	3
Exposure time in final position:	1118 s

Total number of overlaps considered:	7
Total overlap time:	2433 s
Number of overlaps where no X-ray source was found:	4
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:	0

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