    Re: Longterm Sun's GHA and Dec: what's under the hood?
    From: Tony Oz

    Dear Greg, dear Robert,

    I'm one of those who can use something only if I understand what exactly I am doing - in each and every step.

    I'm sure - the long-term table for Sun's GHA/Dec is not very different from the long-term GHAAries table, it just has to account for two more changeable functions (unlike more simple GHAAries ).

    All I need to use those tables - is an overview of what each correction does. What is the variable E? It was allocated this letter for some reason, I guess. It was not for an Elongation, what was it then? Is it the Equation of Time?

    Could someone please pour a light on those tables?

    Thank you in advance.

    Warm regards,


    60°N 30°E
