    Re: What is the best accuracy you can expect from a 'dip-short' table

    As long we are talking about "dip-short," what was the purpose for these tables? If you are shooting a star while standing on the shore or anchored then you already know where you are, you need to know this to know the distance to the waterline you are using for reference line, The only reason I can come up with is for use in convoys where another ship is blocking the horizon below the celestial object being observed. Any other ideas?

    Subject: [NavList] What is the best accuracy you can expect from a 'dip-short' table

    Hi all,
          Does anyone know what is the best accuracy you can expect from a
    'dip-short' table is?
    There are many sources of tables (kinda like opinions) is any one better
    than another?
    Should you use an equation, and is there one particular equation that is
    more accurate than another?
    Thanks,
         ~Greg
