Re: Some variables from November's data set

One more thing.

One of the things that I did for HD932 was to plot about 20 stars that were 
close to it.  This to look for any effect due to position on the 
image.  The nearby stars are all constant.  So I still think that HD932 is 
some sort of variable, no mater what the experts say that look at a couple 
of older measurements and declare that the old experts did not see the star 
change so it must be fixed.  Along these lines, I note that Pojmanski found 
a Landolt "standard" to be varying.  Sigh!  No one is safe from an all sky 
survey.

The position points for this star all form a nice tight group.  I think 
there is little chance that this is a blend of two stars that happen to 
shift regularly due to some measurement artifact, like where they appear on 
the pixel.
