Curses for brain/typo errors.
Last posting by me:-
"Agreed: from calculated true altitude to a calculated apparent refraction, refraction is to be added, as in the zenith diagram in fact".
Should read:

P.S.
On other internet discussion groups/fora it is possible to correct text afterwards for a time; is it not possible to implement this here?
