John, you make a compelling argument. My image scale (50"/pixel) seems to be
the problem here. In this case the two stars in question are only separated
by about 50", resulting in a blended object. This contaminates the
centroiding algorithm. Since they are of similar brightness when at maximum,
I remeasured several images when TbrV0149 was an minimum light (per the
light curve) in order to reveal the "other" star. In all cases, the position
worked out be within a couple of arcsec of GSC 8996-455. So I believe you
are correct. TbrV0149 is GSC 8996-1474.
