Radio image of a remnant radio source. The colourmap is LOFAR-IB, with contours from the LOFAR18 image in green, LOFAR6 in blue, FIRST in red (no detection in the full image), VLASS in yellow, and LOFAR-IB in purple (no detection in the full extent of the source). Contour levels are the same as in Fig. A.1. The inset is showing zoom-in on the expected central part of the source. The red ‘×’ denotes the expected position of the core, and the fact that there is no identification of the optical host galaxy. As denoted with ‘✗’ in the legend, the central region of the source is not detected in any of the radio images.
