Cumulative purity and completeness of the catalog at different S/N cuts for different seasons. Top: cumulative purity at different S/N cuts for the 150, 220, and 280 GHz frequency bands and different seasons, including the coadd maps. The criterion for inclusion of a source in the catalog for each map is taken as S/N₁₅₀ ≥ 5.0, S/N₂₂₀ ≥ 5.5 and S/N₂₈₀ ≥ 5.8 at 150, 220 and 280 GHz (orange, blue and green vertical lines, respectively). Bottom: completeness of the catalog at different S/N cuts for different seasons, including coadd maps. In this case, the same S/N implies a lower completeness at higher frequencies. Note that different seasons behave similarly at a fixed frequency. The coadd maps generally have a greater purity compared to the single-frequency maps, which is expected.
