[vsnet-chat 141] QW Sge comparison stars

[Taichi Kato <tkato@kusastro.kyoto-u.ac.jp>]

  I would like to add a comment on QW Sge comparison stars regarding "Help
wanted. archive plates of AS 360 = QW Sge" (vsnet-chat 138, U. Munari).
QW Sge is one of the object which shows large discordances of magnitude
estimates between obserbsers (have a look at the VSNET light curve of
QW Sge) -- different (inappropriate?) sequences may be responsible.
A V-band chart based on Ouda CCD observations is shown at the URL

  http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/Symbio/qwsge.html

in which QW Sge was measured to be V=12.56 as a combined magnitude of a
close pair.  Hope this helps.
