Caption: Fig. 2.
Composite image of a 2﹩\arcmin﹩ field around RX J0911.4+0551. The frame has been obtained by combining our I‐, J‐, and K‐band data. North is up, and east to the left. Note the group of red galaxies with similar colors, about 38﹩\arcsec﹩ southwest of the quadruple lens (circle), and the group of even redder galaxies 10﹩\arcsec﹩ southwest of the lens (cross).
