DC55 coil gives very large harmonics, the cause which is undetermined.  The integrated strength values seem fine, but because of the harmonics problems 48BC1.6 coil was used for the measurements.  48 BC 1.6 was not ideal because it was possibly a bit short, so quads QS1, QS2, Q2E#1 and QSE#2 were all checked using a stretched wire.

There are calibration runs (2-5) and a diagnosis run (7).
