    Longterm Sun's GHA and Dec: what's under the hood?
    From: Tony Oz
    Date: 2018 Dec 6, 11:59 -0800

    Hello!

    Recently the topic of a table for longterm Sun's GHA and Dec was mentioned, apparently referring to this publication.

    Unfortunately even the "enhanced" version of How-To accompanying that table is rather cryptic (to say it mildly).

    I wonder - what is behind all those look-up tables and corrections to further corrections? Where can I read about the topic?

    As it is published - it looks like an example of the Rules the mariners of Old had to learn by heart and execute as robots...

    Please comment.

    Regards,

    Tony
