    Re: Is there a way to produce Sight reduction tables for air navigation
    From: Dave Walden
    Date: 2016 Sep 4, 05:39 -0700

    Frank is able to produce the entire volumne using an existing set of star selections.  As an exercise, I wrote an excel spread sheet that produces the results for an arbitrary latitude and GHA.  Input is a list of star RA's and Dec's.  I came up with a set of "star selection rules" that weighs angular distribution and brightness and altitude.  I could not find any documentation of how the air nav tables make their selection.  Anyone?
