Hi Tancredi,

I just ran cc_eff.C on run 2602 which was taken last night with field off
and 45mV threshhold.

If I take only the center two TOF paddles, the efficiency numbers are:
left box 0 with TOF 1: 54% with TOF 2 62%
left box 1 with TOF 4: 76% with TOF 5: 73% with TOF 6 71%

right box0 with TOF 1 31% with TOF 2 47%
right box1 with TOF 4 54% with TOF 5 52% with TOF 6 41%

The numbers are under pretty generous cuts that take into account any
coinc's listed in Cuts.C, namely, protons are searched for in paddles
higher than 6. I will look into more strict cuts.

Also, I need to apolagize to Pete, I made changes in TBLScRecon but was a
bit sloppy with maintaining the codes. It cuased problems in his macros
and caused delay in his progress.

Chi
