About tiled field analysis.

So far 5 fields have been scheduled for observations. Data are available and processed for 4 of these.

13815 — 890 s of cleaned data taken between 2020-10-21 08:56:50 and 2020-10-21 13:25:40
13816 — 900 s of cleaned data taken between 2020-10-21 08:59:16 and 2020-10-21 11:56:28
13817 — 945 s of cleaned data taken between 2020-10-21 09:01:40 and 2020-10-21 13:24:33
13818 — 922 s of cleaned data taken between 2020-10-21 09:04:02 and 2020-10-21 12:02:08

3 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.
