| allocError | fatal |
| | Can't allocate memory for internal array |
| badFileMode | fatal |
| | Invalid datamode dataMode in set set |
| ZERODRIFT | warning |
| | OM tracking history
is not present for this exposure so no tracking shifts can be applied
corrective action: No tracking correction will be applied |
| deAllocError | warning |
| | Failed to release memory for name |
| zeroValuedFlat | warning |
| | One or more
elements of the tracking-shifted flat field (usually at the edge) were
unexpectedly found to be zero. This is likely to be a sampling effect.
corrective action: Resets zero valued pixels to unity and sets a non-zero
value in the quality array |
| Uniform flatfield | warning |
| | No flatfield correction will be applied to the image |
The
OM flatfield is currently set to unity (see omflatgen task documentation) so
this warning always appears. This may change in the future. The use of a
uniform flatfield is `unconventional`, hence the warning (notification) to the user.
