Default Total energy probe orientation?

Using the newer esa probe, model DN/3-fach/UN, with the two "prongs".
Does the orientation matter, and if so, which way is correct? * Horizontal
or up/down?

Thanks.

also, comedic replies not needed.

Since the marketing hype for this type of probe is about insensitivity
to angle of attack changes I would presume you are supposed to use
them vertically so AoA changes on both TE prongs balances each others.
Presumably the reason for not putting the TE prong horizontal
(includign on a single prong conventional TE probe) is sensitivity to
slip/skid angle. That and it would look dawky.

I suspect more likely this is an example of a solution looking for a
problem. Try taping over one of the TE ports at a time and let us all
know if it was worth spending the extra money on.
