Abstract:
A new catalog of isolated galaxies from the Sloan Digital Sky Survey
Data Release 5 (SDSS DR5) is presented. A total of 1520 isolated
galaxies were found in 1.4sr of sky. The selection criteria in this
UNAM-KIAS catalog are a variation on the criteria developed by
Karachentseva, including full redshift information. Through an image
processing pipeline that takes advantage of the high-resolution
(∼0.4"/pix) and high dynamic range of the SDSS images, a uniform
g-band morphological classification for all these galaxies is
presented.

Note (1): According to HyperLeda. Code numbers 9 and 10 have been
re-assigned to include Sdm and Sm galaxies.
Note (2): Bar structure code as follows:
0 = absence
1 = suspected
2 = definite
Note (3): Ring code as follows:
0 = absence
1 = inner
2 = outer
3 = both
