Fig. 15.


Left panel: 20″ resolution LoTSS-DR1 mosaiced image of the galaxy cluster Abell 1314; right panel: an image produced from the same data but after improvements to the pipeline described in Sect. 5.1. The colour scale of the images are the same and the contours show the levels where σ = 120 μJy beam−1. The LoTSS-DR1 image of this cluster suffers from artificial haloes around the extended structures and a low dynamic range. The improved LoTSS image has a higher fidelity and is in good agreement with the independently processed image presented in Wilber et al. (2019).
