Abstract:
In this paper we present and analyze new CCD UBVRI photometry down to
V∼21 in the region of the young open cluster Collinder 232, located in
the Carina spiral arm, and discuss its relationship to Trumpler 14 and
Trumpler 16, the two most prominent young open clusters located in the
core of NGC 3372 (the Carina Nebula).
Description:
Observations were conducted at La Silla on April 14-16, 1996, using
the imaging Camera mounted at the Cassegrain focus of the 0.92 m
ESO-Dutch telescope.
