Noise-level comparison of different Virgo cluster surveys. The circles show different wide-field surveys (filled circles) and targeted observations of samples of Virgo galaxies (hollow circles). The marker size is proportional to the angular resolution of the corresponding survey. The quoted noise level for LOFAR refers to the median noise inside the virial radius. The dashed line shows an interpolation of this noise level assuming a spectral index of −0.7.
