About tiled field analysis.
So far 7 fields have been scheduled for observations.
Data are available and processed for 8 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.
