About tiled field analysis.

So far 6 fields have been scheduled for observations. Data are available and processed for 5 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.

1 fields were processed but not included in the analysis. This is because, after standard processing and the removal of times contaminated by light reflected off the bright Earth, there was too little data (<100 s) for source detection to be performed.

Probable afterglow details

A source was found which matches the afterglow criteria.

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.
