Data analysed so far:

ObsID: 00019048001 with 2.0 ks exposure.

About tiled field analysis.

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.

Find an upper limit.

Sources found so far

So far 4 sources have been found in the XRT data. 8 sources match catalogued sources. There are also 6 sources marked as spurious.
