    Weems Star Altitude Curves
    From: Dave Walden
    Date: 2009 Apr 3, 02:28 -0700

    Star Altitude Curves were meant to be used in high speed aircraft.  Older exts 
    on aircraft navigation give descriptions.  (Particularly those by Weems.)
    
    Attached are works in progress.  An excel spread sheet to compute and plot a 
    set of curves.  (Excel's forte is not plotting!)  And a gnuplot input file. 
    (gnuplot is an open source plotting program for linux and windows.)  Turns 
    out to be far from straight forward to label the curves neatly.  Suggestions?
