GMRT 610 MHz images of A68, A1722, RXCJ1212.3-1816, and A2485 in contours (black +ve and cyan −ve) are shown overlaid on the respective Chandra X-ray images (colour). The contour levels are at 3σ × ( ± 1,2,4,8,...) in all the panels (see Table 2 for 1σ levels and the beam sizes). The 0.5−2 keV exposure-corrected Chandra X-ray images with resolution ~4′′ are presented for A68 (Obs ID 03250), A1722 (Obs ID 03278), and A2485 (Obs ID 10439) and an XMM-Newton (EPIC MOS) pipeline processed image (Observation number 0652010201, 0.2−12 keV, resolution ~8′′) for RXCJ1212.3-1816 is presented.
