XWIN-NMR data are stored on disk as 32 bit integer values. To achieve
best accuracy, XWIN-NMR double precision processing shifts data to
exploit the full 32 bit range when converting data ot integer. The
shift number is documented in the processing status parameter NC_proc,
where positive values count the number of right shifts and negative
values count the number of left shifts.
XWIN-NMR internal operations always consider this scaling factor.
For raw data (fids and ser files) the scaling factor is documented
in the aquisition status parameter NC.
3rd party programs comparing different XWIN-NMR data sets must also
consider these scaling factors.
