    Re: Lunars question for Frank
    From: Bill B
    Date: 2005 Oct 6, 23:19 -0500

    Bill you asked:
    "Has the angular distance off  in longitude been adjusted by the program for
    latitude, therefore should be  translated directly into nautical miles by
    converting to decimal degrees and  multiplying by 60, or should an
    adjustment
    be made for latitude when  determining nautical miles off?"
    
    Frank responded:
    
    It's approximate error in longitude so  multiply by cos(Lat) if you want
    nautical miles. Actually, the code is doing  nothing more than multiplying
    your distance error by 30. One of these days I'll  modify it to give a more
    accurate longitude error (which depends on the rate of  change of the actual
    distance but is generally close to  30).

    Thanks again.  Assumed longitude was indeed just that, but second guessing a
    genius is, IMHO, a poor practice ;-)
