Definition:
        The value of _array_intensities.pixel_fast_bin_size specifies
               the number of pixels that compose one element in the direction
               of the most rapidly varying array dimension.
               Typical values are 1, 2, 4 or 8.  When there is 1 pixel per
               array element in both directions, the value given for
               _array_intensities.pixel_binning_method normally should be
               'none'.
               It is specified as a float to allow for binning algorithms that
               create array elements that are not integer multiples of the
               detector pixel size.
