Examples of predictions (black dashed rectangles) for images from the validation set that match the manually created catalogue. These examples are curated to show the model predictions for a wide range of source morphologies. Each image is a 300 × 300 arcsec cutout of LoTSS-DR2 Stokes-I, pre-processed as detailed in Sect. 4.3. The red square indicates the position of the focussed PyBDSF radio component, and the red dots indicate the position of PyBDSF radio components that are related to the focussed component according to the corrected LOFAR Galaxy Zoo catalogue. The green triangles indicate the position of components that are unrelated to the focussed component. ‘x’s (thick marker if related, thin if unrelated) indicate components that we removed, and a black cross on top of an ‘x’ means the component was automatically reinserted after the prediction. In our method, all components that fall inside the predicted black rectangular box (and are not removed) are combined into a single radio source.
