OCR SIS-026 was executed on 3-27-01 to "optimize data return for the
short range, low energy events by slightly modifying the on-board
processing scheme".

Anomalies:
G01-0023 - Station D16's Metric Pointing Assembly (MPA) needed a
complete reboot just prior to the scheduled AOS on 3-25-01 (DOY 084).
While AOS was delayed ~15 minutes, all nominal activities were
completed prior to the scheduled EOT (DR# G06857).

G01-0024 -  ACE experienced ~1 minute data dropout during SSR dump on
3-23-01.  All affected data was redumped; no further problems were
experienced.
