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 |
| Group Number Too High? | All good |
| Non linear? | All good |
| Saturated? | All good |
| % full well high? | All good (60% < 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. |
