J/ApJ/399/353       Radial velocities in Hickson compact groups (Hickson+ 1992)

Dynamical properties of compact groups of galaxies. Hickson P., Mendes de Oliveira C., Huchra J.P., Palumbo G.G.C. <Astrophys. J. 399, 353 (1992)> =1992ApJ...399..353H (SIMBAD/NED BibCode)
ADC_Keywords: Galaxies, optical ; Redshifts ; Velocity dispersion Keywords: galaxies: clustering - galaxies: distances and redshifts - galaxies: interstellar matter - galaxies: luminosity function, mass function Description: Radial velocities have been observed for 457 galaxies in the 100 Hickson compact groups (Hickson =1982ApJ...255..382H; catalog VII/85). Brighter galaxies were observed over the period 1984-1986, using the 1.5m telescope of the F.L. Whipple Observatory on Mt. Hopkins, Arizona, in wavelength range 470-710nm; the remaining fainter galaxies were observed with the Canada-France-Hawaii Telescope (CFHT). These velocities are listed in table2. Dynamical parameters were derived for 92 of the 100 groups, which are listed in table3; Hubble constant was assumed to be Ho=100km/s/Mpc. File Summary:

Heliocentric velocity 33- 35 I3 km/s e_RVhel ? Estimated rms in RVhel 37 I1 --- q_RVhel *[0/2]? Confidence code on RVhel
Note on q_RVhel: the confidence code is 0 = highest confidence: spectral features clearly visible 1 = lower confidence: spectral features not clearly visible 2 = lowest confidence: very noisy spectra with no obvious features. Only 3 galaxies have q_RVhel=2.
