Subject: bfem NSBF pre-ship and post-ship event files

Heather,

I've just now uploaded six 10-minute run Bfem event files to:
  /nfs/farm/g/glast/bfem/data/evt/.

The first three were taken before shipping to NSBF:
 -rw-rw-rw-   1 balloon  other    20949740 Jul 21 09:21 0995718299_0000.evt
 -rw-rw-rw-   1 balloon  other    20071040 Jul 21 09:25 0995718899_0000.evt
 -rw-rw-rw-   1 balloon  other    20344724 Jul 21 09:30 0995719499_0000.evt

The second three upon arrival at NSBF:
 -rw-rw-rw-   1 balloon  other    19779560 Jul 27 18:35 0996271259_0000.evt
 -rw-rw-rw-   1 balloon  other    19531836 Jul 27 18:38 0996271859_0000.evt
 -rw-rw-rw-   1 balloon  other    19625244 Jul 27 18:42 0996272459_0000.evt

[Note: These listings are on the Sun Gse; on the Slac Farm they 
will have Jul 28 dates and be owned by dsl.  Pls. check sizes.]

The Bfem was in nominal configuration (upright, tracker 3-in-row 
trig config 0). However, as Bob's note mentions, we already know
that one Acd channel (Ritz #310) shows intermitent pedestal rise 
in the second set of three files.  Bob's note regarding the new 
Acd channel which fixes this problem will apply to future files.

Nonetheless all six should be converted to root and inspected for 
other anomolies, in a "before/after" sense.  In other words, are 
there any significant changes in Bfem characterstics between the 
first set of three and the second set of three? 

If you need more specific info about the config, I'll have to refer
you to Dave T. or Dan W., who can best interpret the log book entries
for these particular files.

Regards,
-Dave.
