Description:
These tables contain a combination of ground-based and HST archive
data for stellar clusters in 18 nearby spiral galaxies. Structural
parameters for each cluster are measured on HST images, while UBVI
photometry is from ground-based data obtained with the Danish 1.54m
telescope at ESO La Silla, the 2.56m Nordic Optical Telescope in La
Palma, Canary Islands, and the 3m Shane Telescope at Lick Observatory,
California. Photometry in the STMAG system based on the HST data is
also given (table 7) for each cluster for the available bandpasses.
