SDSS_DR10.GalaxyVol* tables
This is a volume-limited subset of the Galaxy table. The table contains only parameters that depend on the group distance which the galaxy belongs to.
Galaxy ID galid is the same as in the Galaxy table. For each GalaxyVol* table thare is a corresponding GalGroupVol* table.
Table structure
| Column | Type | UCD | Unit | Description |
|---|---|---|---|---|
| galid | int | meta.id meta.main | our unique identification number for galaxies (identical with the flux-limited galaxy identification number) | |
| groupid | int | meta.id.parent | group/cluster id, unique within one volume-limited sample | |
| ngal | int | meta.number | richness (number of members) of the group the galaxy belongs to | |
| rank | int | meta.record | luminosity rank of the galaxy within its group; rank 1 indicates the most luminous galaxy | |
| absmag_u | float | phot.mag em.opt.U | mag+5log(h) | absolute magnitude of the galaxy in u filter, k+e-corrected |
| absmag_g | float | phot.mag em.opt.B | mag+5log(h) | absolute magnitude of the galaxy in g filter, k+e-corrected |
| absmag_r | float | phot.mag em.opt.R | mag+5log(h) | absolute magnitude of the galaxy in r filter, k+e-corrected |
| absmag_i | float | phot.mag em.opt.I | mag+5log(h) | absolute magnitude of the galaxy in i filter, k+e-corrected |
| absmag_z | float | phot.mag em.opt.I | mag+5log(h) | absolute magnitude of the galaxy in z filter, k+e-corrected |
| lum_r | float | phys.luminosity em.opt.R | 10+10Lsun/h2 | observed luminosity in the r-band |
| dist_cor | double | pos.distance | Mpc/h | comoving distance of the galaxy after suppressing of the finger-of-god effect |
| crd_x | double | pos.cartesian.x | Cartesian coordinate along the x-axis defined by eta and lambda | |
| crd_y | double | pos.cartesian.y | Cartesian coordinate along the y-axis defined by eta and lambda | |
