    Radar Plotting Sheet for Polaris
    From: Greg Rudzinski
    Date: 2009 Oct 18, 16:45 -0700

    A radar plotting sheet can be used for correcting a Polaris HO to get 
    Latitude. 90° minus Polaris declination will give the diameter of the circle 
    in minutes of arc. The attached example is 90° - 89° 18.4' for a 41.6' 
    plotting sheet circle diameter. Intersect the circle with the LHA of Polaris 
    then measure to the baseline with dividers. The scale at the upper left will 
    provide the correction to better than a minute of arc.
