[vsnet-chat 1039] Re: UV Per Sequences

[aah@nofs.navy.mil]

  Patrick Schmeer asked about the AAVSO stars 120 and 126.  The sequence
in Henden/Honeycutt does not include these two stars.  I don't remember
why, unless it was due to close companions (we tried to use 'clean' stars
wherever possible) or were too bright (I know the 10-11mag comparison
stars in the field were saturated on our frames).  I can go back into the
data and calculate the magnitudes of these two stars if it is necessary
(nice thing about CCD photometry!). However, as Brian said, the vsnet
V-band chart is probably adequate in regard to those two stars.  I checked a
few of the fainter stars, and they agree with our sequence to +-0.02mag or so.
