    Re: Interpolation of Meridional Part Table

    Me previously:
    "[Error is] normal in an obsolescent subject like traditional navigation. "
    
    Peter, you replied:
    "Frank, this seems particularly silly.  Leaving aside this assumption that obsolescence = error"
    
    Peter, sorry. I did not mean to imply that obsolescence EQUALS error. Rather 
    obsolescence leads to lower quality control. When a subject fades into 
    obsolescence (a process that may take decades), it is not uncommon for errors 
    to creep in and propagate simply because there is a steadily declining market 
    for the information and additionally because there are fewer error-checkers 
    and fewer opportunities to publish revisions and lists of errata. 
    
    And you concluded:
    "how can nav that serves an ongoing practical use be considered obsolescent?  
    Its only obsolescent to you because you don't need it."
    
    I know a couple of guys who like to use Morse code --because civilization 
    might collapse, or something like that :-). While the case for celestial is 
    not quite as severe as that of Morse code, there's no question that celestial 
    navigation and other methods of traditional navigation are in steep decline. 
    If you don't want to call it "obsolescence," feel free to use another word. 
    Got any ideas?
    
    Now, back to the "error" that Andres refers to. It turns out it has nothing to 
    do with recent editions of Bowditch so my suggestion that this might be due 
    to the general obsolescence of traditional navigation was wrong from the 
    outset. So is it, in fact, an error? And if so, what explains its publication 
    in such a reference?
