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? | Full saturation: There are 44 pixels saturated at the end of the first group. These pixels cannot be recovered. |
| % full well high? | % full well>80% (147% > 80%) |
| Num Groups Reset? | Optimized NGROUPS below minimum (1). SET TO NGROUPS=1 |
| 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. |
