Comparative view of the reconstruction errors on the simulated images during the experiment of Sect. 6.1. Median values over the 10 repetitions of the experiments are reported with the crosses and the transparent areas cover the interquartile spread. MSE appears on the first row, MAD on the second one. The metrics are computed after convolution with the CLEAN beam. Each column is a different super resolution factor: 2, 5, 10 (from left to right). We observe that the metrics have similar values between CLEAN and the LASSO-based methods (PolyCLEAN and APGD). This indicates that the different algorithms are indeed configured to return images of similar quality and thus the comparison between the solving times performed in the experiment is relevant.
