_diffrn_data_frame.center_units

Name:
'_diffrn_data_frame.center_units'

Definition:

       The value of _diffrn_data_frame.center_units
              specifies the units in which the values of
              '_diffrn_data_frame.center_fast' and
              '_diffrn_data_frame.center_slow'
              are presented.  The default is 'mm' for millimetres.  The
              alternatives are 'pixels' and 'bins'.  In all cases the
              center distances are measured from the center of the
              first pixel, i.e. in a 2x2 binning, the measuring origin
              is offset from the centers of the bins by one half pixel
              towards the first pixel.

              If 'bins' is specified, the data in
                  '_array_intensities.pixel_fast_bin_size',
                  '_array_intensities.pixel_slow_bin_size', and
                  '_array_intensities.pixel_binning_method'
              is used to define the binning scheme.
