Histogram of the redshift distribution of 20 galaxies in the area of SDSS CG 6. The average redshift and the velocity dispersion for the whole sample (20 galaxies) is 0.21981 and 703 km/sec (solid line). The slashed histogram shows the velocity distribution for the 15 non-emission-line galaxies in the sample. For this subsample, the average redshift is =0.21837 and the velocity dispersion is 608 km/sec (dashed line).
