COMMENT:

This is the diffuser calibration table, ARS1 with 2x2 PFI's.
The movie images are still AlMg as is the rule.  The teminator 
filter is ND/Al.1.

In this table I have changed the flare mode sequences. We now cycle
once through each image type, for a total cycle time of 16 sec, and
get two Al.1 FR's during that period. This should greatly improve our
statistics on the QR fixed-exposure images. Yesterday's proton flare
looked a lot like the Aug. 28 1992 event, with dimming motions clearly
caught in the QR images.

PLAN:

The next table is on Thursday at pass 4 (24-Apr-98 04:19 UT), and its ID is 
980423 P4 ARS1 STD.
