Example of two of the stellarity criteria used in this paper to separate galaxies from stars. Left: B- z vs. z- K for all sources in the catalog. The dashed line depicts the BzK criteria of Daddi et al. (2004) to isolate stars. The solid lines delimit the regions where high-redshift galaxies are located. The red dots indicate sources satisfying three or more stellarity criteria. Right: comparison of the magnitude in a 3'' radius aperture ([3.6] _3'') and SExtractor MagAuto ([3.6] _auto), i.e., the concentration parameter, vs. [3.6] _auto for all sources in the catalog. The criterion of Eisenhardt et al. (2004) identifies stars with −0.25 < [3.6] _3'' − [3.6] _auto < 0.2 and [3.6] _auto < 17.80.
