About tiled field analysis.

So far 3 fields have been scheduled for observations. Data are available and processed for 3 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 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.
