Sensitivity of the various deep dedicated surveys covering the Boötes (top) and Lockman Hole (bottom) fields as a function of observing frequency. The resolution of the various surveys corresponds to the radius of the black dot, while the diameter of the corresponding surveyed area is encoded in the size of the gray circle. The LOTSS-Deep Fields pointings are marked with a red cross, and the dashed line corresponds to a source that has a spectral index of − 0.7.
