You should have some considerations, why could h depend on L and N. Otherwise, for broader generality you should also consider dependence on Moon phase, which btw is easier to know for the device than L and N.
I don't know how to react to your post. It looks half-trollish, half-jokish. For a programmer the dependence between those 3 parameters is so obvious that it's impossible to explain to someone else (as most of obvious things).
