Full 3 GHz mosaic as imaged by Smolčić et al. (2017b) of the 2 deg² COSMOS field. The green polygon indicates the footprint of the CANDELS WFC3 imaging (Nayyeri et al. 2017). The inset of ﹩340\,{\mathrm{arcmin}}^{2}﹩ shows the position of the X- and S-band primary beam. Additionally, the seven-pointing mosaic at 34 GHz, part of the COLDz project (Pavesi et al. 2018), is shown with the black contour.
