CARMA 30 GHz observations (Decker et al. 2019) with radio source-subtracted LOFAR low-resolution contours of the available MaDCoWS clusters in LoTSS-DR2. The different beam sizes are shown the on the bottom left corner of each panel, with the solid grey corresponding to LoTSS-DR2 and open white to the CARMA 30 GHz data. The colour map represents the SZ variation in units of signal-to-noise, therefore negative values reveal the presence of the cluster (with the centre marked by the white ‘plus’; Decker et al. 2019). The black circle places the R₅₀₀ area given the SZ coordinates, and the white cross provides the MaDCoWS centre (Gonzalez et al. 2019). The cluster mass, R₅₀₀ and redshift from the CARMA observations are indicated in the upper left corner of each panel.
