    Re: Noon sight for longitude

    Replying to a posting by Jim Wilson, Henry Halboth wrote-
    
    "Don't you just love the attack dog mentality exhibited on this List."
    
    Oh, Henry! Those words were completely uncalled-for by the posting, and
    quite untypical of your usually calm and reasonable approach.
    
     and added "The changes noted can be and are corrected for, if appropriate,
    and within the critic's capabilities."
    
    That may indeed be the case, but unless the article points out to a reader
    the necessity of making such a correction (and it didn't), how can that
    reader know anything about it?
    
    That wasn't the only necessary information that was missing from the
    article. There was no indication of what accuracy (or lack thereof) might be
    expected, under different conditions of Sun noon altitude, and no indication
    of whether certain such conditions might make it unsuitable, or call for a
    longer measurement period. (but then, that's an omission we have seen
    elsewhere).
    
    If such an article is to be useful to its readers, then it should present
    the complete picture, shortcomings and all, and not gloss over the
    difficulties.
    
    George.
