IzH colour image of XMMUJ0044 with X-ray contours overlayed in white and the 3 spectroscopically confirmed cluster members shown with yellow circles (ID numbers refer to Table 1). Left: cluster field image (3′  ×  3′) showing the 4 interlopers (green circles) within 1′. Right: blow-up of the core region (1.5′    ×    1.5′) showing the red-sequence galaxies (white circles) – see Fig. 2. North is up and East is to the left. The XMM-Newton PSF at the cluster off-axis angle is  ~10″ (FWHM).
