Compact groups of galaxies in SDSS DR7
Listed in IVOA Registry (Virtual Observatory)
We investigate the properties of photometrically selected compact groups (CGs) in the Sloan Digital Sky Survey.
Description
In this paper, the fourth in a series, we focus on understanding the characteristics of our observed CG sample with particular attention paid to quantifying and removing contamination from projected foreground or background galaxies. Based on a simple comparison of pairwise redshift likelihoods, we find that approximately half of CGs in the parent sample contain one or more projected (interloping) members; our final clean sample contains 4566 galaxies in 1086 CGs.
