Abstract:
We report on a multiwavelength study of the relationship between young
star clusters in the Antennae galaxies (NGC 4038/9) and their
interstellar environment, with the goal of understanding the formation
and feedback effects of star clusters in merging galaxies.

Note (1): Following the convention used in Whitmore & Schweizer (1995,
Cat. J/AJ/109/960) and Whitmore et al. (1999AJ....118.1551W 1999AJ....118.1551W), the
coordinates are the offsets from RA=12:01:52.97 and DE=-18:52:08.29
(J2000.0), near the center of NGC 4038.
Note (2): The difference in V magnitudes measured in a 1-pixel and 6-pixel
radius aperture, which provides a rough determination of cluster size.
Objects with ΔV1-6<1.0 are likely to be cosmic rays.
Note (3): Duplicated numbers are neighboring objects, generally because of
differences in spatial resolution between the cycle 2 and cycle 5
observations.
