About tiled field analysis.

So far 7 fields have been scheduled for observations. Data are available and processed for 6 of these. The list gives the exposure time used in source detection. If any individual sources were selected for follow-up observations, the source detection is not repeated for the follow up observations and the table below is not updated.

An additional 1 field has also been used for follow up observations. These data are not searched for sources, but are used to update the light curves etc of any sources already found.

09h 18m 33.90s -05° 11′ 52.8″ 7.6′′ Good 15.0′ 288 s Matches known X-ray source: 2SXPS J091833.9-051151 (from 2SXPS), 1.9″ away. Vizier logo

1 Radius, 90% confidence.
2 Indicates how likely the source is to be real. See the 1SXPS documentation.
* The position was enhanced using astrometry derived from the Swift UVOT.
The position was astrometrically corrected using the XRT sources and the 2MASS catalogue.
