    Re: Exercise #11 AM star fix

    Hi Jeremy yes that is correct I will have to breakdown and purchase
    Vol 1 not much on downloaded versions in that aspect I am a bit of a
    purist. When yielding 2 possibilities where would you start a new
    course line? Also you mentioned you averaged your Moon sites but upon
    my graphing them the 21-01-40 and 21-03-22 sites I considered fliers
    and therefore solved 21-00-48, the mid site. Thanks much.
