Low-frequency radio imaging and residuals for RXC J2014.8−2430. Left: VLA 1.4 GHz image of RXC J2014.8−2430, shown on a square-root scale, with contours from the X-ray image in Fig. 1 overlaid. The beam size and position angle are depicted in the lower-left corner. Middle: GMRT 610 MHz image of RXC J2014.8−2430, shown on a square-root scale, with contours from the X-ray image in Fig. 1 overlaid. The beam size and position angle are depicted in the lower-left corner. Right: residuals in the GMRT imaging after subtraction of a Gaussian source model convolved with the synthesised beam, revealing a large residual feature to the west of the AGN. Contours from the X-ray image in Fig. 1 are overlaid. The beam size and position angle are depicted in the lower-left corner, and the scale is linear.
