Digital beam of NenuFAR in the configuration of the NPBS modelled at the zenith for a frequency of 58 MHz. Contours represent the gain attenuation of −3 (corresponding to the FWHM of the digital beam), −6, −9, and −12 dB, respectively. White contours defining the two sidelobes around the main lobe (as well as the outer contours of the main lobe) correspond to the gain attenuation of −12 dB.
