redshift space dimensions

I'm an educated physicist, but I don't know what "redshift space dimensions" of km/s are. (I can guess, but that's not relevant.) I don't know how many readers will. I see no wikipedia article talking about it (if there is, why not link it?), and Googling doesn't help. Why not translate into distance units of one kind or another? I know redshift doesn't *strictly* equal distance, but isn't it good enough for a short wikipedia article about a particular structure in the sky? — Preceding unsigned comment added by 192.16.204.219 (talk) 14:19, 22 July 2013 (UTC)

I may be late to answer this one, but I will answer it still. The unit was used to measure the expansion rate of two objects within its dimensions. Just simply divide it to the Hubble constant (67.80 km/sec/Mpc) times units in megaparsecs. You will get 117 Mpc for 8000 km/s, 73.74 Mpc for 5000 km/s, and 14.74 Mpc for 1000 km/s. ==Johndric Valdez (talk) 08:19, 2 February 2014 (UTC)==
