BCAL time resolution update



Hi All

David Lawrence created a new data file for me for Run 2334.
Attached is the time resolution as a function of energy based
on 0.5*(N-S time difference) for segment 8 after time-walk
correction.  I don't know what changes were made in the
new data file - but I now get a good fit to the conventional
resolution dependence on energy.  Recall the the expected
contribution to the floor term from beam width should be 32 ps.

Will pursue - have to catch my flight.
