Fig. 7
Left column: fraction of galaxies showing [OII] or Hα emission lines, respectively, vs. distance from the cluster centre. Right column: mean equivalent width of [OII] and Hα emission lines for all objects (objects without detectable lines get assigned a lower threshold value) vs. distance from the cluster centre. Top to bottom: total cluster sample (TCS), northern cluster sample (NCS) and southern cluster sample (SCS). Note that for the southern cluster sample the increasing trend only sets in at clustercentric distances >3 Mpc and does not reach the field level before RBCG1 ≃ 6 Mpc.
