    FW: 249 v 229 , Starpath, time tick

    Actually, the GPS (satellite) time is off by about 12 seconds.  Each
    manufacturer corrects for this inside the unit.  Accuracy may be affected by
    internal errors, but I'm sure it's accurate enough for celestial navigation.

    Hello.  I have a few basic questions.  First,  any strong feelings out there
    about the Starpath workforms?  I like them a lot,  I use them with pub229,
    and they seem quite a bit more efficient than Navy-type strip forms.  I
    haven't tried then with NAO method yet.
        Second, is volume 1 of 249 only used for star identificaton, or can it
    be used for reductions as well?  All we  tend to use it for in the Coast
    Guard is as a star finder.  I reduced a star sight using only pub249 and it
    seemed to work, although I'm confused by the fact that it doen't include any
    declination values?
        Third, I've been using DGPS as my time tick for all my sights, (we don't
    have a chronometer).  Is this as accurate as I think it is?
        Lastly, I'm intrigued by what I've heard about 211/Ageton sight
    reduction.  Where can I find out more and/or get a copy of the requisite
    tables/forms/instructions.
    Thanks,
