Quick ?: On a sundial with a split face (for a "significantly thick gnomon"), will a nodus cut into the style still function properly? Of course, the style length itself could be exactly where a nodus would fall, but for ease of construction, I'd imagine that it would be better to include a bit more style, past the nodus.
How would one read the point on the face where the nodus is projected? Same as for the time itelf (ie., from the side of gnomon corresponding to the side of the dial face the gnomon shadow is projected) ? Thanks... john. ... re: the longitude correction "vote" ... the Local dial proponents win... Now, I just have to have a way to mount a handy weather proofed digital calculator under the dial somehow, so that the displayed sundial time can be manually inputed on the spot, and a calculation made so that the standard time will be displayed complete with long and EoT correction.... ;-)
