Radio emission of A 2142 overlaid on the red plate of DSS–2. Black contours show a low resolution GMRT 234 MHz image restored with a beam of 45.2′′ × 40.8′′, PA –37.9° (same as Fig. 1); contour levels are ±3, 6, 12 mJy/b; and the rms in the image is ~0.9 mJy b-1 far from the field centre (negative contours are white dashed). Red contours show the 608 MHz full resolution image restored with a beam of 5.2′′ × 4.5′′, PA 52.6°; contour levels are ±0.1, 0.2, 0.4, 0.8, 1.6, 6.4, 25.6, 102.4 mJy b-1; and the rms in the image is ~35 μ Jy b-1 far from the field centre. Negative contours are shown in white.
