Data were analysed using HEASOFT version 6.35.2


RA (J2000):	19h 42m 39.94s (295.66641)
Dec (J2000):	+46° 24′ 14.4′′ (46.40399)
90% Error radius:	2′′
Number of overlaps included in position:	11
Exposure time in final position:	5851 s

Total number of overlaps considered:	14
Total overlap time:	6992 s
Number of overlaps where no X-ray source was found:	2
Number of low-X-ray-count fits rejected:	0
Number of spurious fits rejected:	1
Number of bad astrometric corrections:	0
