About tiled field analysis.

So far 5 fields have been scheduled for observations. Data are available and processed for 5 of these.

4 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.
