Stab in the dark here (pun intended): Maybe two distinct redshift signatures have been noted with one for close (glob) and one more suitable for galactic separations?

Subject: [TAC] NGC 4147
I was putting together an observing list for next 3rdQ/NM, and found it includes quite a few nice Arp and Hickson catalog entries, some excellent edge-on galaxies and big Abell galaxy clusters. But I also ran into a globular cluster, NGC 4147 - described as "Moderately bright, fairly small, irregular 2'-2.5' diameter,very small bright core." OK, nice for a change after a bunch of galaxies. But, looking at Megastar, it seems to be a foreground object to ESO 287-23, which would be quite a stretch on its own, at 16.5 (0.8'x0.2'). Still, I was curious, so I looked at the DSS image, and, how do they know there's a galaxy there!?!?
