. Thank you Ruediger!

I read this many years ago and recently my interest in the apparent apex phenomenon was rekindled and I could not for the life of me remember enough about this paper to find it.

There is one definition in there that my years had fuzzied. You would think if not Altec, at least I would have remembered Ted Uzzle coauthored.

Safely stored now thank you!

All the best,
Barry.
