Run under stored command load P22e. Has new ACIS parameter
files which do not use FEP 0.

Next Comm 294:04:55--05:45 (00:45 on 21 Oct, EDT).

NOTES/ISSUES/PROBLEMS
chandra.snapshot is not updating.

ACIS FEP error monitor on terminal MALANG is beeping. Jim
Francis diagnoses this as a telemetry drop from squirt.
When this happens, call the following until someone is reached:
Jim Francis 253-2044
Peter Ford  253-7277
Royce Buehler 253-9766
Bev LaMarr  258-8153
Click the print screen and print the PMON screen (far right
vertical window). Then restart that screen by typing q, and
up-arrow enter to recall the command and restart the display.

Quick look plots.
CXCDS Ops is now making quick look plots of the immediately 
previous day or two, for a quick check of operational data
quality.  This notebook is "Quick Look" on the top tray at
the SOT-LEAD station. We should look at this daily and note
any "funnies."  Note that this is proprietary data which 
must be properly protected; e.g., kept in the TST room 
where keypass access is restricted. Further plans may be 
to have these images available as *.gif files in a password
protected area of the internal web.
In Today's look, OBSID 581, deep southern field, shows 
the extremely high rates in S2, and also higher than normal
in I3, which we expected from the errors in mapping FEPs 
to their bias parameters. OBSID 320, NGC1399, shows
wipeout of S3 -- this may be presumed to be due to the use
of FEP-0 as we were not able to intervene with a realtime
correction.

At the 9am meeting it was reported that ~5hours 20 min of 
data was irretrievably lost due to equipment malfunction
at the Canberra ground station. The missing data started
290:19:00. It affects OBSID 334 of Q0836+7104: we got 17 hours
out of 21 planned; and OBSID 012 of II Peg: we got ~12 1/2
hours out of 14 planned.  These are both very near exceeding
the minimum required for a complete observation.
