One very important technical note is appropriate here, which highlights another practical advantage of the routine usage of the in situ compensation outlined in this report. We strongly emphasize that the compensation for the unbalanced signal of the empty C-CSH has been done by a simple subtraction of the results reported by the magnetometer in the respective *.dat files. The only restrictions to be enforced on the system are: (i) to per-form the T-dependence with the "Auto Tracking" option set on, and (ii) to use the "linear regression" algorithm.
