• 16185 — 729 s of cleaned data taken between 2023-07-26 14:09:44 and 2023-07-26 14:23:43
• 16186 — 709 s of cleaned data taken between 2023-07-26 14:24:20 and 2023-07-26 14:36:47

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.
