Thanks, Greg. This makes perfect sense now.
The only thing I still can't wrap my head around is why this seems so much simpler than the Ageton method I am familiar with.

Stan,
Attached is a Sun Hc reduction done today showing a side by side single column reduction using a trig calculator and the Ageton Classic method. Hope this helps.

This results in a nine page table, rather than the 36 page table of the original H.O. 211 (which I thought was already pretty compact).However, your method works differently than the Ageton (or Ageton-Bayless) that I am familiar with. Attached is a screen shot of the Celestial Tools "Ageton Compact" output using the input data from your example and the format right out of the book. Yours seems simpler, and does not involve a K value. Only one of the table values is the same in both methods. Apparently I do not yet understand how you are doing it, and my head already hurts, so please walk me through when you get a chance.(BTW, I noticed that there are two different values of Hc on the index card.)Stan
