Hi Jason,
I agree with Haiyan that the results are encouraging. It's my
recollection that the asymmetry at low Q^2 is expected to be about
10% with a 50% product of P_b*P_t. Do you agree with that. We
calculated it for the expected try in December.
The one thing that puzzles me is the error bars at backward
angles are only about 2-3 times larger than the errors at forward
angles. With this short a run, the errors must be limited by
statistics, in which case I would expect the errors at the back
angles to be much larger, unless the cuts are letting in lots of
background counts in which case we are not looking at the ep
asymmetry at those angles.
