Doesn't matter which row or column in Table 5?

[EdCa]

Here's and odd question- does it matter whether you use the column for minutes of declination or "d" correction from Pub. No. 249 to get the proper "d" correction?  By this I mean I've discovered that whether 249 specifies any "d" correction (45 for example) and the Sun's declination for a certain day and time (let's just say 21 minutes of declination) the same correction value of 16 can be found whether you use 45 minutes of declination and a "d" of 21 or 21 minutes of declination and a "d" value of 45.  No matter which way you  arrange it you still get a d correction of 16.

That would let me think that Table 5 is goof proof- you'll still get the same d correction value.

What do you think?

Thanks,

Ed
