Performance comparison of two BSS methods in the astrophysical case, evaluated as a function of input noise level expressed in terms of S/N: LCS (orange) and LPALM (blue). Each data point represents the mean and standard error over 150 realisations from the test set of Fahes et al. (2021). Left panel: average PSNR for the source estimates (S). Right panel: average CA for the mixing matrix estimates (A).
