Never mind!  I just stumbled over those lines in selfuncs.c where
indexCorrelation is calculated by dividing the correlation of the
first index column by the number of index columns.

I have a use case here where this clearly is not the right choice and
was hoping to find some examples that help me investigate whether my
case is somewhat uncommon ...
