Description:
Table 4 lists photometric data for Young Massive Star Clusters
identified in a sample of 21 nearby galaxies. The photometric data
have been corrected for Galactic foreground extinction. Each cluster
is identified by the abbreviated NGC number of its host galaxy and an
object number: nxxx-yyy is object number yyy in the galaxy NGC xxx.
Effective cluster radii have been obtained by modeling the cluster
images as MOFFAT15 functions convolved with the point-spread function
measured on the CCD images.
