Information on resource 'A Manually Cleaned List of Nearby Galaxies from SDSS DR9'
We present a sample of 317,018 galaxies at the redshifts 0.003 < z <
0.1 from SDSS DR9.
We arrived at the current selection by limiting z as computed by SDSS,
filtering out non-galaxy objects, and finally checking for faulty and
duplicate objects. This yielded 724,000 objects.
Further cleaning steps included removal of quasars and star-like
objects, removal of duplicate images using the SDSS DR9 Image List
Tool as well as proprietary code. By visual inspection, we selected
the best image of each galaxy, which led to a sample of about 360,000
galaxies.
Using the SDSS recommendation to avoid typical statistical errors near
the spectroscopic flux limit we restricted the sample by stellar
magnitude in r-band (modelMag_r < 17.7).
