_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.
