Source ILTJ134255.151+541432.752. The background rgb image in the top panels is bands g, r, z from the Legacy Surveys as in Fig. 9 but here it is smoothed with a 2D Gaussian kernel with width = 0.8′′. The white contours in the two top panels are from the DR2 processing of this field, while the red contours are the LOFAR-VLBI imaging of this source. Bottom left panel: DR2 image and contours, while bottom right panel: LOFAR-VLBI image and contours. The LoTSS contours start at 10σ and increase by until either the data maximum is reached or nine levels have been drawn, while the LOFAR-VLBI contours start at 7σ and increase by until five levels have been drawn. The restoring beam for the radio images are shown in the bottom two plots.
