[vsnet-chat 1669] Re: U Sco sequence

[aah@nofs.navy.mil]

Bruce has presented a nice sequence for this field.  I thought
the VSNET chart (at least the one in the web site announcement)
was based on Tycho magnitudes, and I would have thought those
values would be better than 0.1mag.  Is Bruce looking at an
earlier chart?  If the VSNET chart is too bright by 0.1mag,
and the three stars in common with Menzies are fainter than
my photometry by 0.07 or so, then there exists considerable
confusion as to who is correct in this region (these questions
should not affect the visual observer, however).  I second
Bruce's request for additional BV photometry of the field,
and not just in the 11.5-12.6 range.  Brian -- do you know
of any sequences in the literature?
