John, it occurred to me that if you wanted to use Zonwlak to put beads on
specific dates on the Analemmas, one way to do that would be to have Zonwlak
include declination lines for those dates. Then when you import it into
DeltaCad, place beads (closed circles) on the proper intersections of
Hi John,
I thought about a procedure in zw2000 to calculate the beads of the EoT
curve but the procedure is rather difficult to build in my program.
The procedure itself isn't difficult, but to get it correct in my program
needs a lot of programming time.
I need a different system for counting
Hello All:
Ron Anthony and I have been having a discussion concerning the proper date
sequence of a beaded analemma (an analemma which has dates marked on it).
We noticed that the Shadows sundial generator program has analemmas with the
following dates of each month: 1,6,11,16,21,26. Why would
Hi all,
Doug Bateman's excellent noon window dial at the Defence Evaluation and
Research Agency, Farnborough, is essentially a beaded analemma with one

I won't venture to guess the motivation of creator of the Shadows
program, but I will
