  #merger? z values indicate relatively close?

  Are you looking at SkyServer for the redshift?

  Yes, Photo Z. Correct?

  Where about on Skyserver? There are several 'z' values that are not actually redshift values 😕

  top right?

  Aahh, I see where you are looking! Very rough estimate, with no spectra to back it up, very unreliable. I do think it is a merger...

  ... from visual observation. I guess I don't need to say this, but Skyserver can sometimes be incorrect 😃

  Or overlay? Sorry, haven't been around since Zoo #1, lots of spectra data then. 😉

  No worries! There is still loads of spectra available on SkyServer, but sadly not for these galaxies! 😃 I will keep digging...

  Thanks, good to know about the z values. Are big z values still used to identify quasars?

  Not really 😃 more about the emissions themselves. I am not a spectra expert - prefer GL modelling. For spectra @budgieye 😃
