Re: Dip: Astronomical Almanac vs. Nautical Almanac

Hi Brad,

Yes we discussed this very recently on the basis (at least on my side)
of the Nautical Almanac. It appears to me that there is a noticeable
difference between the two Almanacs. If my interpretation would be
correct then the dip would differ between the two Almanacs by
Diff[moa]=0.36[moa]*sqrt(H[m]). I am just wondering whether this
difference is "real" or only resulting from some misinterpretation.
According to my understanding the equation which you indicate should
have brackets and read A  - [ D(H) - R(H) ], but I may have missed
something already before.

Marcel
