I also write astronomical algorithms and astronomical software. And I
also use Meeus for my inspiration.
Meeus, though an astronomer, also recommends measuring from South, but I
have decided over several astronomical products to continue measuring
from North, which more laymen are familiar with.

Dear Friends
Thanks for the positive comments!
And thanks to Gianni Ferrari, Patrick Powers, Edward French and Jack
Aubert for pointing out the MAJOR error in the Annual Equation of Time
Table.
It was giving EoT values /across/ the table instead of /down/, which
is an error I had corrected before - but had crept back in....!
That has been corrected.... Many apologies
Also, by popular request, I have changed the sign of EoT from the
strict astronomical convention to the more usual gnomonical convention
(the correction to get from sundial to local mean time).
Gianni also wants Azimuth measured from the South... I am a 0 deg at
North person. Any thoughts ? I will probably change things to give a
radio button, so you can choose.
I have had requests for a solar noon table and solar east/west table
and a half-minute Victorian table - which I shall implement in due course
Best wishes
Kevin
