Comment: Giovannini et al 2013
Redshifts: 4 Deimos masks observed through Dec. 2013; the number of
members is just an estimate.
Imaging: we have VLT imaging but of too small an area: only the
"A3411" area in the above right image. There is evidence for a
another galaxy concentration (different cluster name: A3412) at the
location of the relic based on shallow DSS images (above left). The
X-ray emission from A3412 may be a point source; there may be no gas
because it has been stripped by the merger with A3411. In any case we
must put slits on both subgroups (A3411+A3412). There is no redshift
in the literature for A3412 but for now we'll assume the same as
A3411.
