- Once the calibration
described in the overview section is done, one can get the wanted

- particularly,
a new calibration has to be done
after the substitution of the complete target castle,
if the vertical alignement values are changed

- ...position
- the reference position must be detected once when
installing the target and when checking the alignments of the reference points with
the metric rulers on the top of the scattering chamber; in this case, we considered
reference position the waterfall target position, with zero degrees angle; changing
the target block, a new reference point must be detected
