Beginning of ReadMe : 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 ================================================================================ ADC_Keywords: Clusters, galaxy ; Photometry ; Redshifts Keywords: clusters: general - methods: statistical - surveys Abstract: In this paper we present an objectively defined catalog of 459 small, high-density groups of galaxies out to z 0.2 in a region of 6260deg^2^ in the northern sky derived from the Digitized Second Palomar Observatory Sky Survey. Our catalog extends down to r=19.0 and has a median redshift of z_med_=0.12, making it complementary to Hickson's catalog (Cat. VII/213) for the nearby universe (z_med_=0.03).
