    Re: Using star-star distances
    From: George Huxtable
    Date: 2008 Sep 22, 23:23 +0100

    In [6296] I wrote, about the effects of aberration-
    
    "This can cause a
    worst-case difference of about 0.7 �, between a star-star distance and its
    value six months later.  John Karl has tabulated his star-star distance to
    0.1 �, but the numbers can not be relied on to anywhere near that 
    precision."
    
    But I labelled the units wrong. It should, of course, have been-
    
    "This can cause a
    worst-case difference of about 0.7 ', between a star-star distance and its
    value six months later.  John Karl has tabulated his star-star distance to
    0.1 ', but the numbers can not be relied on to anywhere near that precision.
    
    Sorry about that.
    
    George.
