**NEW** SDSS DR7 Host-Satellite catalog (plain text): CLICK HERE

Each line contains the SDSS ObjectID number of a host, followed by the total number of satellites, followed by the SDSS ObjectID numbers of each of the satellites.


SDSS DR7 Host Information catalog (gzipped): CLICK HERE

This catalog contains relevant information about the SDSS host galaxies. The columns are as follows:

column 1 = SDSS ObjectID number
column 2 = RA (in decimal degrees)
column 3 = DEC (in decimal degrees)
column 4 = redshift
column 5 = angular diameter distance (in "true" Mpc)
column 6 = ellipticity of r-band image as measured by the SDSS
column 7 = position angle of r-band image as measured by the SDSS (N through E),in degrees
column 8 = r-band magnitude
column 9 = (g-r) color, k-corrected to redshift zero
column 10 = log10(Mstellar/Msun)


SDSS DR7 Satellite Information catalog (gzipped): CLICK HERE

This catalog contains relevant information about the SDSS satellite galaxies. The columns are the same as in the host catalog above.


AAW's DR7 Host Information catalog (gzipped): CLICK HERE

This catalog contains the shape information in all 5 SDSS bandpasses (u,g,r,i,z) for the host galaxies, as computed by Professor West. The columns are:

column 1 = SDSS ObjectID number
column 2 = u-band position angle (N through E), in degrees
column 3 = g-band position angle (N through E), in degrees
column 4 = r-band position angle (N through E), in degrees
column 5 = i-band position angle (N through E), in degrees
column 6 = z-band position angle (N through E), in degrees
column 7 = error in u-band position angle (N through E), in degrees
column 8 = error in g-band position angle (N through E), in degrees
column 9 = error in r-band position angle (N through E), in degrees
column 10 = error in i-band position angle (N through E), in degrees
column 11 = error in z-band position angle (N through E), in degrees
column 12 = u-band ellipticity of the image
column 13 = g-band ellipticity of the image
column 14 = r-band ellipticity of the image
column 15 = i-band ellipticity of the image
column 16 = z-band ellipticity of the image
