Meta Index / Home Page
This section documents warnings and errors generated by this task (if any). Note that warnings and errors can also be generated in the SAS infrastructure libraries, in which case they would not be documented here. Refer to the index of all errors and warnings available in the HTML version of the SAS documentation.
| ||Can't allocate memory for internal array|
| ||Invalid datamode dataMode in set set|
| ||OM tracking history
is not present for this exposure so no tracking shifts can be applied
corrective action: No tracking correction will be applied
| ||Failed to release memory for name|
| ||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 |
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.
| ||No flatfield correction will be applied to the image|
