2. 2 The test shim geometry is based on Gary McGinnis shape and general layout.

3. 3 A2 metrology dataA1 metrology data Edge data was taken on side-A of A1 modular coil whereas surface data and edge data was taken on side-A of A2. Flange edge data Flange surface data

4. 4 Chart shows the surface variation on A2 for points taken on the flange edge.
