Completeness magnitude limits for ground-based imaging. Left panels: Distribution of the SExtractor magnitude inside an 8.0″ diameter as a function of the magnitude inside a detection aperture of 1.5″ diameter for BVRiz bands. The horizontal and vertical dashed blue lines indicate the detection and completeness limits, respectively. The continuous red lines are the linear relation between the magnitude within the 8.0″ diameter aperture and the magnitude within the detection aperture, minus/plus 1σ (dashed red lines). Right panels: Number counts of galaxies for each band. The dashed blue lines mark the completeness magnitudes.
