RA is in hours-minutes-seconds (0-235959), and dec is in deg-min-sec (-90 to
90 deg). The z value is the redshift of the star/body, which can be used for
distance estimates.

Except they're not stars.  They're galaxies.

True, that particular sample of data was all long range stuff. I've been
looking for redshift data on more local astronomical bodies, but haven't had
much success. Have you found any sources for a file full of star redshift
data?
