Total intensity radio contours of the A781 system at 325 MHz with the VLA in B+C+D configuration. The image has a FWHM of 46.1′′  ×  52.0′′ (PA = −71.8°). The contour levels are drawn at  −2.9 (thin-dashed lines), 2.9 mJy beam^-1, and the rest are spaced by a factor of 2. The sensitivity (1-σ) of this image (not corrected for the primary beam) is 0.95 mJy beam^-1. The image primary beam corrected has a sensitivity (1-σ) of 2.2 mJy beam^-1.
