Table 4
#1
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.
