COMMENT:

This is the standard dark calibration table, ARS1 with 2x2 PFI's.
The movie images are still AlMg as is the rule in this table.
The teminator filter is Op/Al.1.


PLAN:

The next table is on Wednesday at pass 3 (22-Apr-98 03:43 UT), and its ID is 
980421 P3 ARS1 DIF.

We may experiment with the flare table to incorporate more Q res fixed
exposure images, better at seen ejecta and possibly waves. The present
plan is to leave the FFIs doing just AlMg for the rest of the week.
