I retract the addendum. I wrote it with the notion that the noon-line should be under the style. …as if the dial were intended to read for its own longitude.
So, sorry—disregard the addendum (…as you probably already have). The dial-plate’s rotation in its own plane should be to correct the style’s pointing-direction (in altitude or azimuth), as I originally said & described. Correcting its altitude would give an easier equation-solution.
