| indx | OBJECT_POSITION
in the NYU VAGC [Note] The 318 galaxies with indx>3000000 are not in the NYU VAGC photometric catalog. Out of the galaxies, 295 galaxies are found in the SDSS CAS and 23 galaxies are found only in the NED. |
| ra, dec |
RA and DEC (in degrees, J2000.0) |
| redshift | redshift [Note] Some of them are negative. |
| Rgal | Comoving distance in units of h-1
Mpc [Note] Ωm=0.26 and ΩΛ=0.74 were assumed. |
| rabsmag | Petrosian absolute magnitude at
r-band normalized to the z=0.1 epoch. [Note] This is calculated from extinction corrected AB fluxes and the evolution correction of E(z)=1.6(z-0.1) is made (Tegmark et al. 2004). |
| urcolor | u - r color [Note] We use model
magnitudes that are extinction and K-corrected to the z=0.1 |
| morph_class | 1 if Elliptical or lenticular, 2
if Spiral or irregular, 9 if photometry failed. |
| morph_type | >0 if Normal late types, 1 if
Normal early types, 2 if Blue early types, <0 if Abnormal late and
early types. To use galaxies with morph_type >0 are recommended. |
| Δ(g-i) |
The difference in g-i
color of the region with R<0.5RP from that of the annulus
with
0.5RP<R<RP, where RP is the
Petrosian radius at i-band.
A negative color difference means bluer outside. |
| conx | The inverse concentration
index at i-band with seeing correction, cin = R50/R90 where R50, and R90 are the radii from the center of a galaxy containing 50%, and 90% of the Petrosian flux. |
| rpmag | Galactic extinction corrected
(Schlegel et al. 1998) Petrosian magnitude at r-band |
| epetR / epetRc |
Petrosian radius at i-band /
Petrosian radius at i-band re-calculated by using elliptical
annuli [in unit of arcsec] |
| iso_a / iso_b |
Isophotal major and minor axis
lengths at i-band, respectively |
| abtrue | Seeing corrected isophotal b/a
axis ratio at i-band |
| phi_iso_deg | Isophotal position angle at
i-band in unit of degree |
| vdisp / vdisperr /snmedian |
Velocity dispersion in unit of km s-1, σ [Note] spectral with median per-pixel S/N >10 and 70 < σ <420 km s-1 are recommended to be used / Error in velocity dispersion: negative for invalid fit / Median per-pixel signal-to-noise |
| rdev, ab_dev / rexp, ab_exp | DeVaucouleur radius (in unit of
arcsec) and b/a axis ratio at i-band, respectively. Exponential radius (in unit of arcsec) and b/a axis ratio at i-band, respectively. |
| morph_err | -1 (default), -9 if objects are
errors in
deblending, blank field, stellar objects, and so on. Do not use objects
with morph_err=-9 [Note] The objects with morph_err=-9 are already excluded. |
| mpmag |
Galactic extinction corrected
r-band Model magnitude |
| grcolor | A rest-frame color K-corrected
to the redshift of 0.1 |
| devmagg,devmagr,devmagi |
Extinction corrected de
Vaucouleur apparent
magnitudes at g-band, r-band, and i-band, respectively |
| expmagg,expmagr,expmagi | Extinction corected Exponential apparent magnitudes at g-band, r-band, and i-band, respectively |
| ztype | Source catalog of the redshift. See Table 1 in Choi et al (2010). |
| matchdist | Angular separation between the matched objects in degrees. For 23 UZC galaxies without SDSS photometry, matchdist = -9. |
