_diffrn_detector_element.reference_center_units

Definition:

   
    The value of _diffrn_detector_element.reference_center_units
    specifies the units in which the values of
    '_diffrn_detector_element.reference_center_fast' and
    '_diffrn_detector_element.reference_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.
