Here are a few more useful ways to use Ageton Pub 211. This AB table makes short work of solving for prime vertical and amplitude. See Example.

This same Ageton table can be used to solve the classic spherical triangle by substituting log cosecant for log sine and log secant for log cosine. The benefit will be the simplification of summed logs. The Ageton table lists log cosecant in column A and log secants in column B. Example SR attached.
