A ??-distribution function is used to represent the normalized size distribution of Albunex??? particles n ??? ( R ) = { A ??? ( R - R 0 ) ?? - 1 ??? ??? - ?? ??? ??? ( R - R 0 ) R > R 0 0 R ??? R 0 , ( 13 ) where ??, ??, and R0 are parameters determining the shape of the function, and A is a normalizing constant for the distribution.
