[vsnet-alert 10199] UBVRI near NGC 300

     Here is a fairly complete UBVRI photometric sequence around NGC 300.
It includes stars observed by Graham, by Alcaino & Liller, and by Walker.
The results by Walker are to be preferred when there is a choice, though the
differences are very small amongst the other observers.  I show all the
data for each star, so for the brighter stars there can be two or three
entries.  The bibcode at the end of each line shows where the data come from.
For some of the Walker stars, I show Graham's U-B colors if Walker does not
give them explicitly.  Graham's and Walker's data are tied directly to
Cousins E-region primary standards, while the Alcaino & Liller data are
from Menzies and Landolt standards (i.e. E-region and Landolt equatorial
standards mixed).
     The sequence spans the range 8.7 < V < 22.0 and 0.0 < B-V < 1.5.
The fainter blue stars are A0 supergiants belonging to the galaxy.
Note also the additional extensive BVI photometry of faint stars by
Pietrzynski et al (http://cdsarc.u-strasbg.fr/viz-bin/Cat?J/PASP/114/298),
which covers a large area in and around the galaxy at high angular
resolution.
