    Re: Lunars Workshop
    From: Frank Reed CT

    A special thanks to Stan for posting his  comments on the Lunars Workshop
    which toook place on September 10. Sorry it's  taken me so long to get back to it.
    
    And also big thanks to everyone who  attended from this list! We had about
    twenty people altogether, but the real  enthusiasts were the Navigation-L list
    members.
    
    Of his first lunar  distance observation, Stan wrote:
    "My first sight was 0.1' off, which is  considered good. "
    
    Good? It's great! And by the way, when I cleared it  again later, the error
    on that sight turned out to be 0.0 so you were right on  the money. This fits
    in well with my experience with lunars. If you have a good  sextant (not
    superior, just "good") and a reasonably careful observer --even a  beginner, lunars
    can easily be taken with an accuracy of 0.2-0.3 minutes typical  error in the
    distance (and frequently less) corresponding to a longitude error  of 6-9
    minutes. But equally important, when the error turns out to be larger, as  with
    the one problem sextant that day, lunars are an excellent means of testing  the
    instrument.
