Dave,

How about noise on the asymmetry measurement? How much ripple is 
allowable on the mini-torus field so that the noise is less than say 
10% of counting statistics on Qw? A small change of deflection of 
elastic electrons could modulate the event rate nicely, especially at 
the small angle side of the acceptance where the cross-section slope is 
large.
