Summary of density map sensitivity experiments for “Best case” SECCO observations. Light-grey squares indicate ≥5σ but <10σ over-density detections, and dark-grey squares correspond to ≥10σ over-density detections; the filled squares outlined in black correspond to cases where the CMD provides significant support to the detection. Light open circles are dwarf galaxies in the LV in the considered range of M_V from the catalogue by McConnachie (2012). The three panels correspond to compact (upper panel), average (middle panel), and diffuse (lower panel) galaxy models.
