    Unfortunately, it's been several years since I tried coding the
    Explanatory Supp. formulas (on an HP-15C) and I can't remember exactly
    what happened. My recollection is that the UTM values I got were close
    to correct, but the size of my discrepancy indicated something was
    definitely amiss. Careful proofreading of my code didn't turn up any
    mistakes. Eventually I gave up.
    
    I never found out the nature of the typo in the book, and I can't even
    swear that there was one. But I have a dim recollection of seeing
    someone mention it online. That was years after I failed to get my
    program working.
    
    Who knows, maybe the problem was me all along, and George's routines
    will work just fine.
    
    Incidentally, I've read that a revision of the Explanatory Supplement
    is in work.
    
    I've never heard of any typos in the DMA publication I suggested, but
    I haven't used its formulas either.
