A vanilla FORTRAN program that generates Gaussian + DC offset distributions for satellite velocities can be found HERE.

An input file for the above program can be found HERE.

A vanilla FORTRAN program that locates host and satellite galaxies can be found HERE. This is a simple program that locates hosts and satellites using isolation criteria along the lines of Sample 1 and Sample 2 from Brainerd (2005), ApJ, 628, L101.

The data file from the SDSS DR3 that is needed to run the program is called "sdss_gals.DR3". A gzipped, tarred version of the data file can be found HERE.

An input file for the host and satellite finding routine that uses the Sample 1 criteria can be found HERE.

An input file for the host and satellite finding routine that uses the Sample 2 criteria can be found HERE.
