Dear D. Labes!

❝ […] See for instance Helmut's last famous lecture

THX for calling it "famous".

❝ […] the term sqrt(2/N) has to be replaced by

❝   sqrt((1/n1+1/n2)/2)

❝ which gives different non-centrality parameters and in turn different power values if n1 not equal n2.

Right.

❝ # modified code to account for "unbalancedness"

Great. I guess you are considering updating your package.
