Multiplicative bias as a function of the nearest neighbour distance. The distance is measured in the input catalogue after removing faint galaxies whose r-band input magnitude > 25. The x-axis values correspond to the weighted average of each sub-sample selected to estimate the multiplicative bias shown on the y-axis. Top panel: the individual biases measured from the blending-only variable shear simulations (magenta points) and the blending-only constant shear simulations (dark green points). The vertical dashed lines show the threshold we set when building the blending-only simulations. Two extra dark green points beyond the threshold are calculated from the full constant shear simulations. Bottom panel: the difference between these two estimates (varShear – constShear).
