CALFOC performs the sequence of processing steps listed below. These steps may be selected (or de-selected) by the values of certain keywords in the header of the input science image. If a processing step is selected, other keywords in the input science image header must contain data such as the names of reference files.
The following keywords select steps to be performed by CALFOC. The steps are performed in the order indicated. The acceptable input values are (PERFORM | OMIT | COMPLETE | N/A). N/A and COMPLETE have the same effect as OMIT. In the output science image (.C0H and C1H), those keywords which were set to PERFORM in the input science image and for which processing was successfully performed are set to COMPLETE.
