S/N maps for the joint detection that matches RXC J0211.4-4017, a MCXC cluster not detected by Planck or SPT situated at z = 0.1 with M₅₀₀ = 1.65 × 10¹⁴ M_⊙. The three colour images show the S/N corresponding to the SZ filtered maps (left), the X-ray filtered map (middle) and the joint filtered maps (right). The filter size is 0.8 arcmin, which corresponds to the one that provides the best S/N for this detection. The angular size of the images is 68.7 arcmin. The RASS exposure time at the position of the detection is 946 s.
