J/AJ/130/425  Catalog of distant compact groups of galaxies (De Carvalho+, 2005)

A catalog of distant compact groups using the Digitized Second Palomar Observatory Sky Survey. De Carvalho R.R., Goncalves T.S., Iovino A., Kohl-Moreira J.L., Gal R.R., Djorgovski S.G. <Astron. J., 130, 425-444 (2005)> =2005AJ....130..425D

Our catalog extends down to r=19.0 and has a median redshift of zmed=0.12, making it complementary to Hickson's catalog (Cat. VII/213) for the nearby universe (zmed=0.03). File Summary:
