 The residual is an indication of how well the calculated data was fitted to the
measurement data. A good fit is indicated by a residual of under 1%. A residual
of over 1% may indicate use of incorrect refractive index and absorption values
for the sample and dispersant.
 The statistics of the distribution are calculated from the results using the
derived diameters D[m,n] - an internationally agreed method of defining the
mean and other moments of particle size. See British standard BS2955:1993 for
more details.
