Hudson, D. McKenzie Date: 2 February 1999 16:00 JST Subj: SXT Table upload for Tuesday, Pass 4 Pass 4: 2-Feb-99 20:53 JST (2-Feb-99 11:53 UT) Table ID: 990202 P4 ARS2 DARKCAL ########################################################################### This table has been transferred to KSC. ########################################################################### COMMENT: This is a special table in support of the Sac Peak flare campaign coordinated by Gianna Cauzzi. FFIs are the dark calibration sequence, and the terminator is Al.1 PFIs are 1x1 and in ARS2 mode to follow the active region at the NW limb (P.A. 66 degrees E of N). Please be aware that SXT lost another piece of its entrance filter over the weekend, so that the stray light has increased. This has had a major cosmetic effect on the Al.1 filter, as usual, which will be a problem for a few days until we can get a terminator image. PLAN: The next upload is scheduled for Pass 2 on Wednesday afternoon. It will be similar to this table. Pass ID will be "990203 P2 ARS2 STD".
