Notes. Group ID, Number of galaxies linked by the FoF algorithm, RA: group centre right ascension (J2000), Dec: group centre declination (J2000), vcm: mean group radial velocity, σv: radial velocity dispersion, Rvir: 3D virial radius, ℳvir: group virial mass. Groups in this table were identified using a FoF algorithm with a contour overdensity contrast of 433, and having four or more members, mean group radial velocities greater than 3000 km s-1, and virial masses greater than 1012ℳ⊙h-1. The complete table can be found at the CDS.
