The "bris" I am hacking is made of a beam-splitter glass (30%-70%). If there is no welding glass infront of it - I can see the Moon very often.
Since the normal "bris" calibration process takes care of refraction, dip and parallax of the Sun - the label of each reflection is (if I'm not mistaken) the geocentric altitude - HC - which must be different for the Moon - because the parallax hugely differs between the Sun and the Moon.
The tables you've posted from Pub211 - as far as I understand - will not help me to obtain a (properly located) Moon LoP from a Sun-calibrated "bris".
I may be wrong everywhere above.
