[BLAST_ANAWARE] data recrunch

Just to let you know that due to some urgency today at noon I starting
recrunching runs 9719-9723 9725-9728 (H2) and 9202-9241, 9268-9300 (D2)

with lrn_v3.3, the right k-factors and beta-cut. With this condition we
obtain the "best" results on H2 elastic this year (see attach). It
fixes the "bad" proton momenta and it improves all other variables. The e-
momentum is still poor (5%). All previous runs are backed up in
/net/data/4/Analysis/recrunch_saved

The cruncherd will take care of putting all info in the database. I am
using all computers, and currently there is only 27 runs waiting. I expect
this to finish sometime tomorrow

Next, there is a priority to redo the april hydrogen data. While
the plan still is to extract flasher based offsets for D2 runs, this
can not be done for this data set since some flasher channels were
missing.

However as soon as chris' offsets are ready you should go right ahead.
The "full featured" recrunch of D2 data may not occur before me
and michael come back. There we will need a "smarter" lrd (no
offense to anyone!) and may entertain new clustering/neural net/calibrations
