Comment: CLASH 2012
CLASH cluster. Radio paper: Bonafede et al 2012. They have hi-res spectral index maps of the relics, so it may be worth asking if they have such data for the galaxies also (to see which way they are moving). The polarization number comes from this paper too (see their Fig 4). The figure below is their Fig. 1.
The two redshifts are from extra slits in Marusa's hi-z mask.
