Average source reconstruction performance of 2D-1D Net, Deflation Net, and CLEAN, over the test sky cubes with (upper sub-panel) a fixed test PSF cube and the noise levels σ_ϵ ∈ {0,1,2,3,4,5,6); (lower subpanel) a fixed noise level σ_ϵ = 3 and the 50 test PSF cubes. Regarding all of these inferences, sources in the test sky cubes have different input S/N_s. These S/N_s values can be divided into ten deciles. This figure visualizes NRMSE_S averaged over sources in each decile. The black whiskers indicate the standard deviations.
