Data Manipulation Description
The raw data, stored in a file named 'mapping.bin' was treated in 3 steps:
1. Conversion from the linear oder of the measurement sequence into two-dimensional order, consitent with the measurement grid as well as separating the three field components
2. Unification of the time axis of each record, using second order interpolation along the time axis 3. Longitudinal shift of the measurement grid in order to eliminate the lack of a mechanical reference
point, using second oder interpolation along the beam axis.

*) - comparison of a magnet with itself gives zero offset
**) - cross check of the algorithm - swapping data should inverse the sign only
