Columns: 1: Authors of the group catalog, 2: SDSS sample and release number, 3: number of galaxies, 4: number of groups ($n \geq$ 2), 5: number of groups ($n \geq$ 4), 6: redshift limits for sample galaxies, 7: FoF linking length in radial velocity, for z=0, 8: FoF linking length in the projected distance in the sky, for z=0, 9: fraction of galaxies in groups ($n \geq 2$), 10 fraction of galaxies in groups ($n \geq 4$).
Notes: 1 For Weinmann et al. groups the linking lengths are in the units of the mean galaxy separation; 3 for Berlind et al. groups the richness $n \geq 3$. * For Berlind et al. the apparent magnitude limit was $r \leq 17.5$, for the rest $r \leq 17.77$.
* Group-finders:
Merchán: FoF + mock catalog + iterative group re-centering + Schechter LF for LL scaling.
Goto: FoF + group re-centering.
Weinmann: FoF + DM halo mock catalog + group re-centering.
Berlind: FoF + DM halo mock catalog.
This paper: FoF + density/luminosity relation in groups for LL scaling + Minimal Spanning Tree.
