    Errors in USNO celestial data
    From: Gary LaPook
    Date: 2010 May 01, 02:52 -0700

    I like to use the navy's celestial navigation data website as the
    standard for comparing other computations at :
    
    http://aa.usno.navy.mil/data/docs/celnavtable.php
    
    
    I sent the following to them:
    
    I was looking for data for 0744 Z, July 2, 1937, 7 -00 North, 158-00
    east and found a bug in your program as it puts out incorrect data for
    mars. At 0743 it gives incorrect data for Alphard.
    
    Similar errors at 7-20 N, 152 E for July 2, 1937 at 0459 Z error for sun
    data; 0312 Z error in Sun and Venus data; 0809 error in Mars data.
    
    It appears that there is a bug in the program. These errors were glaring
    and easily spotted but I calls into doubt all of the data that might
    have subtle errors.
    
    see attached image of erroneous data.
