                          throws java.lang.Exception

This method returns the ratio between the current basal area and the optimal basal area according to the yield tables.

Parameters:

species - a AWSTreeSpecies object

age - an integer

hDom - the dominant height

basalArea - the current basal area (m2/ha)

Returns:

the optimal basal area (a double)

Throws:

java.lang.Exception
