Fig. 1.


Image rms, frequency, and angular resolution (linearly proportional to the radius of the markers) of LoTSS-DR1 in comparison to a selection of existing wide-area completed (grey) and upcoming (blue) radio surveys. The horizontal lines show the frequency coverage for surveys with large fractional bandwidths. The green, blue, and red lines show an equivalent sensitivity to LoTSS for compact radio sources with spectral indices of −0.7, −1.0, and −1.5, respectively.
