The File  021307_VVSA1_FLUX_LOOP_MEASURED.MC9 contains all of the Flux loops as measured in the installed position on the vacuum vessel. The points reflect the center of the 3mm probe tip. The alignment files were also saved reflecting the position of the vessel in the rotissery to help determine vessel deflections. Some Global fiducials are for reference only and change proportional to the vessel rotation in the rotissery fixture.

The decision was made to change the method of measurement after a number of loops were already scanned.

1. A single spline and point group represent data that was aquired by probing the center of the two wires

2. A double spline and point group represent data that was aquired by scanning the outer and inner surfaces around the loops contacting both the surface and the loop wire

3. Some (Complementry Loops) were scanned using both methods

4. THO3 scan contains some Data from THO2 and 4 as a location reference

There is also another element that must be considered.
 
Some of the surface scans (Type 2 and 3)  were made by discontinuing data aquisition at each loop hold down (inconel Band-aid) eliminating a .005 band-aid thickness. The rest aquired data by continuing over the bandaids and must be filtered accordingly.
