Globular cluster candidates in ACS Virgo survey.

Listed in IVOA Registry (Virtual Observatory)

We present catalogs of globular cluster candidates for the 100 galaxies of the Advanced Camera for Surveys Virgo Cluster Survey, a large program to carry out imaging of early-type members of the Virgo Cluster using the Advanced Camera for Surveys (ACS) on the Hubble Space Telescope.

Description

We describe the procedure used to select bona fide globular cluster candidates out of the full list of detections based on model-based clustering methods with the use of expected contamination catalogs constructed using blank field observations and which are customized for each galaxy.

We also present the catalogs of expected contaminants for each of our target galaxies. For each detected source we measure its position, magnitudes in the F475W (~Sloan g) and F850LP (~Sloan z) bandpasses, and half-light radii by fitting point-spread function convolved King models to the observed light distribution. These measurements are presented for 20375 sources, of which 12763 are likely to be globular clusters.

Finally, we detail the calculation of the aperture corrections adopted for the globular cluster photometry.
