Detection efficiency of searches for satellites for KiDS-like catalogue-level simulation (chain C). The detectability ranges from 0% (dark blue) to 100% (bright yellow) as a function of the V-band absolute magnitude, physical half-light radius, and heliocentric distance. The 50% detectability limits fitted by polynomials (n = 3) are shown in yellow dashed lines. The detectability limits of image-level simulations are plotted in red dashed lines. The satellites found within KiDS footprint are overplotted in the detection efficiency map.
