The list below shows coordinates and UBVRI photometry for stars in the
field of the large open cluster IC 4665. Most of the data are from the work
of Menzies & Marang (1996MNRAS.282..313M). They observed the stars on at least
three nights each from South Africa directly against Cousins E-region primary
standards. The observations of the stars in SA 109 show how well they match
the Landolt system.
For one IC 4665 stars and for two more in the near region, I show Landolt
data for comparison and to extend the standards collection. L83a indicates
data from the main 1983 Landolt paper (1983AJ.....88..439L), L83b the
"equipment stability" paper (1983AJ.....88..853L), and L92 indicates the main
1992 standards paper (1992AJ....104..340L).
