    Re: S-tables: where to have a look at them?

    Apparently you responded again since I started writing my last post.  I expect that the last time you looked at it was before this morning so I did not take offense, and even if you were commenting about today's version of the table I know it's incomplete so I still don't take offense.  That an the fact that I have very thick skin from my profession as a construction inspector, where one of the duties is to tell people anger management issues "No."  That's not to imply that you have anger management issues, just that that's where I got the thick skin.

    I would propose the following for the article:

    Title change to Sight Reduction Methods. (Sight reduction as a whole arguably includes all the data processing from just after taking the sight to the point you are ready to plot.  This article seems to be about just the spherical trig portion of sight reduction.

    Section explaining the point of the spherical trig reduction and why various methods were developed

    Section explaining the calculator method 

    Section explaining the difference between Inspection Tables and Mathematical Tables and explaining that there were also some slide rule formats

    Section on historical methods.

    • Sine/Cosine tables
    • Haversine Table
    • Secant/Cosecant Tables
    • Log versions of the previous
    • Rust
    • Ogura
    • HO-203/204
    • HO-218
    • ?

    Section on methods that gained wide-ish use in english speaking world

    • Current table
    • Bygrave
    • Weems
    • Reeds Tables
    • ?

    Section on non-english speaking methods

    • Yugo slavia - K tables
    • France - Doniol
    • USSR - ?
    • Japan - ?
    • China - ?
    • ? - ?

    Section on recent developments

    • Brown-Nassau
    • Hav-Doniol
    • Hanno Ix azimuth diagram
    • Harold Gatty Watch only system
    • LaPook

    By Stan's last email, I infer that you were the last person to update the tabular methods Wikipedia article.  I meant nothing personal about you and your efforts.  I was unaware that the current version of the article was your effort.  I feel confident that someone will be along shortly to mangle what you have written.
    My technical comment remains true.  The article does not reference HO203/HO204, among the very first of tabular methods.  It is a complete solution, like HO249 and HO249.
