Examples of using the SDC to subtract contaminant lines. In locations where secondary lines from neighboring slits impact the main line (ground truth with Poisson noise in red, from model C (top row) and model B (middle and bottom rows)), SDC inversion results can be used to remove the effects of these secondary lines (blue) from the MUSE signal (black) and isolate the estimated main line (green). The main differences between the ground truth (red) and derived main line are due to photon noise.
