I compared runs 7100-7107 (60 cm cell) and runs 5858-5910 (40 cm cell
from 3/25/04). Here are the results:
electron left:
qel qel && abs(z) <
20 qel && abs(z) < 20 && cerenkov
60 cm 12.9
11.24 9.25 (events/coulomb)
40 cm 7.79
7.5 6.22
lectron right:
qel qel && abs(z) <
20 qel && abs(z) < 20 && cerenkov
60 cm 13.2
11.54 9.5 (events/coulomb)
40 cm 8.0 7.7
6.39
So the situation may not be that bad. The quesi-elastic cut is very
loose, basical all events with momentum higher them 0.62 GeV/c. I'm not
sure what precipitated the result that I sent before. I'm using
stricter cuts in my analysis and it seems like a resolution became
worse. I also use some timing cuts that might have shifted. I will
adress this shortly.
Cheers, Vitaliy
