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? | Partial saturation: 4158 pixels are saturated in group 2 and higher and will not be used in the calculation of SNR. Reduce Groups per integration and increase Integrations per exposure if you want to use all groups in the ramp for the calculation of SNR. Partial ramps may still be used in some cases. |
| Saturated? | All good |
| % full well high? | % full well>80% (175% > 80%) |
| Num Groups Reset? | All good |
| Minimum Integrations? | All good |
