Finding charts for two cluster candidates from Fig. 2. Coloured 2′ by 2′ SDSS images are overlaid with XMM X-ray contours, produced from co-added MOS and PN images in XMM bands 2 and 3. The red circle indicates the extended X-ray source position and extent as provided by 3XMM. The red crosses indicate the positions of point-like X-ray sources. The yellow and light blue circles denote likely cluster members with spectroscopic redshift indicated by purple circle and label where possible. See text for details.
