    George,
    
    Thank you once again for explaining another point very clearly.
    Regarding your medal, I was attempting to present you with what I
    would covet as an award, but fear it came across too baldly, slipping
    out before the final polish was applied.  I very much enjoy the
    humour in your posts, except perhaps when they're aimed at me.
    
    I can see I hashed the analysis, but the intention was accurate.
    
    In noon sights, would one ever correct for third-order effects such
    as acceleration or decceleration in the declination, say around the
    middle of May?  These would be much smaller than your 15-second
    correction, mis-shaping your parabola around noon but not changing
    the point of inflexion unless you tried to measure it with only two
    readings.  Compared to clock errors in the old days, the 15-second
    correction due to the change in the declination doesn't sound like a
    major one.
    
    Thanks,
    
    Fred
