Errors

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.

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.

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
