Hi Gregory,

Sorry for the delay in sorting out possible differences. Apart from 
differences in counts, I haven't seen any other major differences in 
asymmetries.  In original comparison, you had slightly lower asymmetry, 
but also slightly lower <x>, so I didn't see any inconsistency. As you 
could see from Raffaella's plot on momentum dependence, there is a 
strong dependence on the e' momentum, correlated to x of the DIS events, 
so some differences in cuts there may generate some differences in DSA.

For now (with Ahmed and Lamiaa) we try to fix the nuclear MCs, so can 
study in details the dilution factors, and compare them with what we get 
from data on C and empty targets. I'll focus on the cuts and detailed 
comparison of asymmetries, when I'll be back to US.

Best,

Harut
