ADC_Keywords: Galaxies, nearby ; Associations, stellar ; Photometry, HST ; Morphology Keywords: galaxies: evolution - galaxies: individual (M51, NGC 5194, NGC 5195) - galaxies: interactions - galaxies: spiral - galaxies: star clusters Abstract: We present a catalog of star clusters with VF555W<23mag detected in the interacting spiral galaxy M51 system based on mosaic images taken with the Hubble Space Telescope Advanced Camera for Surveys by the Hubble Heritage Team. We have selected about 3600 clusters based on their morphological information through visual inspection. The final star cluster catalog includes 2224 clusters that are relatively well isolated and have a circular shape. Description: The data used in this study were obtained by the Hubble Heritage Team to commemorate the HST's 15th anniversary using the HST Advanced Camera for Surveys (ACS) with F435W, F555W, F814W, and F658N filters through HST observing program 10452 (P.I.: Steven V. W. Beckwith). The observed field is as large as about 6.8'x10.5' centered on NGC 5194. File Summary:

Note (1): Source extraction flag as follows: 0 = star cluster is well isolated 1 = cluster has neighbors 2 = cluster is originally blended with another source but deblended by SExtractor 3 = cluster has a neighbor and is blended with it but deblended by SExtractor Note (2): Comments as follows: FF = cluster is classified as a faint fuzzy cluster FFt = not explained in the paper
