Completeness in the versus plane as inferred from extensive MC simulations. The completeness given by the color scale represents the fraction of sources recovered by PyBDSF (resolved and unresolved) over the original number of mock sources. The blue points show the position of resolved SFGs in the VLA COSMOS 3 GHz map studied in this work. White contours represent a completeness levels of 5, 25, 50 and 75%.
