4. Preferred redshifts
Further confirmation of the physical reality of the association comes from the similarity of redshifts of the quasars in the alignment. In Fig. 2, five of the six quasars in the alignment (counting 3C 345 at z = .59) average to z = .61. It is very unlikely, on the assumption that these are unrelated background quasars, that they would be so closely the same redshift.
A sixth quasar in the close alignment is at z = 1.08 and the outer quasars in the group are at redshifts which agree closely with the quantized redshifts found in all analyses of quasar redshifts, namely:
