If requiring 3 (>5 sigma) detections is the threshold, I'm trying to understand what is happening with limit/unforced vs forced photometry values

e.g. https://star.pst.qub.ac.uk/sne/atlas4/candidate/1104825400250936200/ aka ASASSN-18hb (AT 2018aqi). On the first night (58209), there is one detection and three upper limits in the top unforced photometry plot (and unforced data table). Then when forced photometry is run, they are all detections (or <5 sigma are then plotted?).

This is in a z=0.011 galaxy so would be in the fast-track eyeball list but only on the second night of detections? It would be great if the fast-track list automatically had forced photometry running and we could have flagged this much earlier.
