• 31953 — 2.0 ks of cleaned data taken between 2011-03-27 10:44:57 and 2011-03-27 12:25:38

6 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.

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.
