- Data analysed so far:
- ObsID: 00019596001 with 2.0 ks exposure.
So far 1 fields have been scheduled for observations. Data are available and processed for 1 of these.
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.
Details of afterglow candidates
1 sources were found which matches the afterglow criteria.

1 Radius, 90% confidence.
2 Indicates how likely the source is to be real. See the LSXPS documentation.
3 T=Transient Source, O=Outbursting known source, U=Uncatalogued X-ray source, K=Known X-ray source.
* The position was enhanced using astrometry derived from the Swift UVOT.
† The position was astrometrically corrected using the XRT sources and the 2MASS catalogue.
Sources found so far
So far 3 sources have been found in the XRT data. 2 sources match catalogued sources.
