Hi Analemmatic dial aficionados:

If you look closely at an analemmatic dial face drawing I made from Roger
Bailey's new Delta Cad Macro for Banff Canada, you can see that the blue
sunrise and sunset lines intersect the major axis line in the same general
area but not exactly at the same point. (see PDF attachment).

There is not really a Bailey Point but a Bailey Zone. But for practical
purposes, it is convenient to think of this as a single point.

On the Picture Rock table analemmatic, I considered the Bailey Point to be
where the Solstice lines intersect the major axis.  But you can see from
close inspection of the drawing that it would be more precise to use a point
that is midway between the solstice line intersection and the Oct-1 line
intersection.

Does this seem like a good way to determine the "average" Bailey Point
location?
