CALWFP performs the sequence of processing steps listed below. Most of 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, it may require that other keywords in the input science image header contain necessary data (e.g., the name of a reference file).
The following keywords select steps to be performed by CALWFP. The steps are performed in the order indicated. The acceptable input values are (YES | NO | DONE). DONE has the same effect as NO. In the output science image (.C0H), those keywords which were set to YES in the input science image and for which processing was successfully performed, are set to DONE.
