    [sorry for sending this twice. I inadvertently left the subject blank the
    first time.]

    Bill, you wrote:
    "Trying my hand at Lunars. In the results on the Frank/Centennia Software's
    calculation screen, there is an angle given above "Corrected for
    oblateness." I am unable to correlate that angle to anything I am aware of
    at this point in my journey."

    How did it go?

    The unmarked angle you've noticed was there for debugging purposes at one
    point. I decided to leave it in and unmarked just for fun --a little mystery for
     the users. It's nothing important, but would you like to try guessing? I'll
    give you a hint: it's an angle that you need to calculate (well actually,
    only it's cosine) as an intermediate number in direct triangle solutions for
    clearing lunars.
