Subject: Realignment of period 1 coils

Tom,

Below are the ProE CS0 Coordinate Transformations for each coil in the first period. These are based on 
collectively realigning all coils to target the resonant field errors (3/5, 3/6, 1/2) they generate 
themselves. This results in a much smaller realignment magnitude than could be achieved with individual 
coils or even like coils (targeting the A's together lead to ~0.060" realignment which is way outside my 
comfort zone). The second and third periods will be handled in a similar way.

When I get updated tooling ball data for the A1 and A2 coils I will calculate the realigned coordinates.
