Warnings

Pay attention to these warnings! If you do not see 'All good' written in each box, reconsider your run.

Value
Group Number Too Low? All good. Ngroups=1 is a new mode since Cycle 4 and has not been rigorously tested. Proceed with caution.
Group Number Too High? All good
Non linear? All good
Saturated? All good
% full well high? All good (76% < 80%)
Num Groups Reset? All good
Minimum Integrations? All good
Exposure Duration? APT will warn that the exposure duration exceeds 10,000 seconds. NIRSpec BOTS permits longer exposures, but a high-gain antenna repoint may cause an approximately 60-second flux excursion.
