Catalog of Visually Classified Galaxies in the Local ($z\sim0.01$)
  Universe
  The morphological types of 5840 galaxies were classified by a visual
inspection of color images using the Sloan Digital Sky Survey (SDSS) Data
Release 7 (DR7) to produce a morphology catalog of a representative sample of
local galaxies with $z<0.01$. The sample galaxies are almost complete for
galaxies brighter than $r_{pet}=17.77$. Our classification system is basically
the same as that of the Third Reference Catalog of Bright Galaxies with some
simplification for giant galaxies. On the other hand, we distinguish fine
features of dwarf elliptical-like galaxies to classify 5 subtypes: dwarf
ellipticals (dE), blue-cored dwarf ellipticals (dE$_{bc}$), dwarf spheroidals
(dSph), blue dwarf ellipticals (dE$_{blue}$), and dwarf lenticulars (dS0). In
addition, we denote the presence of nucleation in dE, dSph, and dS0. Elliptical
galaxies and lenticular galaxies contribute only $\sim1.5\%$ and $\sim4.9\%$ of
the local galaxies, respectively, whereas spirals and irregulars contribute
$\sim32.1\%$ and $\sim42.8\%$, respectively. The dE$_{blue}$ galaxies, which
are recently found populations of galaxies, contribute a significant fraction
to the dwarf galaxies. There seems to be structural difference between dSph and
dE galaxies. The dSph galaxies are fainter and bluer with shallower surface
brightness gradient than dE galaxies. They also have lower fraction of galaxies
with small axis ratios ($b/a \lesssim 0.4$) than dE galaxies. The mean
projected distance to the nearest neighbor galaxy is $\sim260$kpc. About $1\%$
of local galaxies have no neighbors with comparable luminosity within a
projected distance of 2Mpc.
