Notes. The ‘Flux density’ column refers to the integrated flux density of the Crab Nebula, including the pulsar. The LOFAR LBA map is from de Gasperin et al. (2020), and the VLA C-band map is from Bietenholz et al. (2015). The VLA L-band map was imaged from calibrated visibilities downloaded from the VLA archive.
