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.
