Hi, Roderick,
My home internet connection is still non-functional so I can't fix it
yet, but it does seem that I will have to add an extra test to handle
southern hemisphere locations and reducing latitudes. Actually, I
originally had a southern hemisphere check in there but took it out
after convincing myself the same frame of reference (x axis east, y axis
north, z up) applied to the spherical trigonometry irrespective of
hemisphere. Ho hum.

Hi Steve,
For both examples below with all sundials at the same Longitude. The
instructions indicate:
Place the wedge-sundial assembly on a horizontal surface in a nice
sunny location. *Start with the higher end of the wedge to the north*
and the sides aligned on a north-south line and the sharp edge should
be on an east-west line.
Example 1:
If you have a sundial that was designed for Latitude -20 deg. And
relocate it at Latitude -50 deg.
Would you start with the higher end of the 30 deg wedge to the North.
Or would it be to the South?

Please correct me if I am wrong. I think that both examples would be
to the South.
