Subject: C1-4 Realignment Coordinate Transformations in ProE
nomenclature

 Tom,

I've translated the C1-4 Realignment Coordinate Transformations to ProE nomenclature for the two cases I previously provided. The first case (designated r1) is the larger motion case where each coil is realigned to cancel its own field errors. Below are the Origins (translations) and Orientation (rotations). I've verified within ProE that they produce the same transform matrix (using ProE Analysis -> Measure -> Transform) as in yesterday's email.
