Position offsets between our 0.3″ radio source detections and optical counterparts according to the 6″ catalogue from Kondapally et al. (2021), where we used selection filters based on the accuracy of the associations at 6″ as described in the text. Left panel: two-dimensional hex-bin histogram with the RA/DEC offsets (dRA and dDec) between the 0.3″ catalogue and the optical counterparts. The median offsets are given by the black dashed line at dRA = 0.094 ± 0.093″ and dDec = −0.067 ± 0.064″. Right panel: position offsets of the selected 192 sources at 0.3″ resolution, where the colourbar corresponds to their absolute offsets and the arrow direction to their directional offset. We added the positions of the DD calibrator with red crosses and the in-field calibrator with a red star. Facets are given by black contours.
