[Michael Dugger]

Volker,

We noticed the -10deg negative shift but do not know how to accommodate 
for it right now. We have included the phi-offest due to transverse 
holding coil.

Can you clarify the statement:
"the data indicate that the measured asymmetry is shifted towards positive 
phi values, perhaps by up to +20deg." I do not know what plot you are 
refering to for the 20deg.

Once Robert has returned from the poster session, our plan is to fully 
understand what is causing the data to look like it is shifted in phi. We 
think that is the last thing to be understood before the data can be made 
publishable.

Take care,
Michael
