    Re: Interpolation of Meridional Part Table
    From: George Huxtable
    Date: 2009 Mar 26, 13:51 -0000

    In [7780], I requested Navlist members to test an equation which I had 
    failed to get to work.
    
    Andres has kindly sorted out my problem, so I can say to anyone who has 
    dashed for his calculator or computer - desist! The problem is now 
    understood. It was in my deteriorating eyesight. Sorry about that.
    
    The equation I quoted had an expression in brackets, which was raised to a 
    power, and I had read that exponent as "1/2", where it was, actually 
    "epsilon/2". That makes all the difference! Actually, it was much clearer in 
    the somewhat-magnified attachment to the list than it was in the tiny 
    characters of the original printed text, in which, even knowing with 
    hindsight where the error lay, I had to use a magnifier to convince myself 
    that it really was so.
    
    So putting matters right, that expression now gives meridian parts for 
    latitude 45�, as 3013.648, to compare with Bowditch's book-value in table 5 
    of his 1981 edition (part 2), of 3013.6.  So, no discrepancy there to worry 
    about.
    
    George.
