Anyone who has read Table 4 instructions will agree that they are most confusing... I think I know why - there is an error in the document.
Here is the problem: Read along if you have table 4 instructions handy.
OT = Jan. 18d 04h - 7h = Jan. 17d 21h. (so far so good)
Main Table, Jan. 17d OT, E 2 33 (- 5) Dec. S 20 51 (- 12) (still good)
Table b for 20h OT - 4 - 11 (PROBLEM)
AH- here is the problem; the 20 should read 21 as per the OT line above. If the OT was in fact 20, the DEC correction -11 would change to -10)?
Jan.17d 20h OT, corrected E 2 29 (SAME PROBLEM)
Here again the 20 should read 21 as per the OT line above.
These small errors made my life a living hell as I tried to figure out from where they got the 20.....
After realizing the error and a few practice problems I compared the GHA and DEC with an Almanac, I noted only a small difference between the two; less than a minute. That's not too bad for a few sheets of paper good for almost two score years of Sun GHA and DEC data.
