3-colour image (R, G, B for Ks, H, Y) of the 20″ × 20″ field of view around MRC 0156-252 (North is Up, East Left). A is the radio galaxy. B and C, previously reported in Pentericci et al. 2001, are respectively selected by the r-YHK and b-YHK criterion. An additional component, D, is also found aligned with MRC 1056-252, B and C but too faint in Ks to be classified by our near-infrared criterion.
