 Upper rejection bound for the set of white reference pixels, in the normalized [0,1] range. White reference pixels greater than or equal to this value will be rejected for calculation of color correction factors. This parameter allows you to reject saturated pixels, or pixels with very high values pertaining to the nonlinear regions of most CCD response curves. Note that since the maximum allowed value for this parameter is one, white (saturated) pixels are always excluded from the set of white reference pixels.
