Notes. Flux densities were extracted from 8.0″ resolution images, created with uniform weighting and a uv-cut. The reported flux densities are measured after masking the contribution from the NAT. The regions, where the flux densities were extracted, are indicated in the right panel of Fig. 5. Absolute flux density scale uncertainties are assumed of 10% for the uGMRT and LOFAR, 4% for the VLA L band, and 2.5% for the VLA S-band and C-band data.
