Okay, how did you know that one has a different redshift? What did you look for?

I have now learnt that I was wrong about how to get redshifts. Sorry! Look at Budgieyes post below mine.

center target galaxy z = 0.02, small blue photoz is 0.03
zErr 0.05, or 0 to 0.08, so inconclusive.

I think that small galaxy is more blue, therefore closer, but that is just me.

The note in NED, says no evidence of interaction, no proof other than looking, which we can see that for ourselves 😃

I thought someone there looked at the spectroscopy at least. If you say no evidence that means you looked for it as much as you can..

Neither galaxy has a spectra associated with it, so visual inspection is most likely the extent of the investigation.
