Paul:

It's been a long time since I read (and reread) the section on many SR
methods. Thanks for the reminder.

As for the Weems credit, here is what Ageton says in the preface (Par 2):

"With all the wealth of research which has taken place in celestial navigation
since the turn of the century, it would be virtually impossible to produce a
method which is original in its entirety. In the construction and arrangement
of Table I, mention must be made of Souillagouet, Bertin, Newton, Ogura,
Aquino, Weems, Dreisonstok, and Gingrich, the works of all of whom the author
has studied."

Further, he acknowledges his own work of table II published as HO 211, plus
other sources and instructors at the USNA.
