Figure 13 - Distribution Functions Following Equations [6a] and [6b] 



The curves I to IV have been derived from the TMB models (Figure: 

 14- and 15) by reducing the coefficient of £ to unity. The procedure of ob- 

 taining the symmetric and the skew part from graphs is obvious: The first 

 one is the arithmetic mean of the fore and afterbody ordinates r) = * 9 — — 



and the latter one the difference
