Greg,
How does this differ from the Ageton-Bayless compact version of H.O. 211? I see you have sin and cos values, but I'm not sure why. They are needed to create the A and B values, but are not used in the computation of intercept or azumuth. I also see the B value has tenths, where Ageton-Bayless rounds to whole numbers.

A prototype 1' sight reduction table (8 standard pages front and back) has been made using Ageton AB log cosecant secant values * 100,000 framed by the corresponding natural sine cosine values. Trials have gone very well. Fast and error free. A 10' wallet version is planned (1 page front and back). When all the bugs are out then a PDF will be posted.
