Abstract:
We present the statistical properties of a volume-limited sample of
7429 nearby (z=0.033-0.044) galaxies from the Sloan Digital Sky Survey
Data Release 7. Our database includes morphology distribution as well
as the structural and spectroscopic properties of each morphology type
based on the recent remeasurements of spectral line strengths by Oh
and collaborators. Our database does not include galaxies that are
apparently smaller and flatter because morphology classification of
them turned out to be difficult. Our statistics confirmed the
up-to-date knowledge of galaxy populations, e.g., correlations between
morphology and line strengths as well as the derived ages. We hope
that this database will be useful as a reference.
Description:
We present properties of 7429 nearby galaxies at the redshift range
0.033<z<0.044 from the SDSS DR7 database (2009, cat II/194; obsoleted
by cat. V/139). We released our morphology catalog including various
spectroscopic and photometric properties (Table6).

Note (2): Ratio between r-band Petrosian radius at 90% and 50% light.
Note (3): Relative to the Sun and derived from the method developed by
Bell et al. (2003ApJS..149..289B 2003ApJS..149..289B)
Note (4): Calculated from the formulae by Graham et al. (2005AJ....130.1535G 2005AJ....130.1535G)
and Cappellari et al. (2006MNRAS.366.1126C 2006MNRAS.366.1126C). Values are discarded when
the criteria (c90/50<3.5 and 10<σ<400) is not satisfied.
Note (5): Provided by the OSSY catalog (Oh et al., 2011ApJS..195...13O 2011ApJS..195...13O).
Note (6): EWFe=(EW5270+EW5335)/2 (Gorgas et al., 1990MNRAS.245..217G 1990MNRAS.245..217G).

Note (8): Class as follows:
0 = Weak-emission (A/N≤1, where A is the best-fitting amplitude of the
emission line being considered and N is the level of noise in the residuals
of the gandalf fit, see Oh et al 2011ApJS..195...13O 2011ApJS..195...13O for details);
1 = Star-forming;
2 = Transition region;
3 = Seyfert;
4 = LINER;
5 = Unclear (1<A/N<3).
Note (9): Relative to the Sun and derived by Gultekin et al.
(2009ApJ...698..198G 2009ApJ...698..198G) using velocity dispersion. Null values if
null values in sigma column.
Note (10): For non-AGN galaxies. A null value is assigned for AGN host galaxies.
Note (11): this ratio (luminosity in [OIII] divided by the effective
velocity dispersion to the fourth power) is related to the black hole
mass accretion rate. A null value is assigned for non-AGN
Note (12): Number of galaxies within a cylinder with 1Mpc radius and
