Notes. The morphological and photometric parameters reconstructed by EM are compared with the ground truth and with the values provided by CLEAN (with FOHM we denote the integrated Flux Over Half Maximum, i.e. the flux above 50% level). The positions are in arcsec; the total flux and the FOHM are in photons cm−2 s−1.
