Notes. The biases when only the basic reduced shear correction is used, when only the basic magnification bias correction is used, when the combined bias from these two corrections is used, and when the IA-enhanced lensing bias correction is used, are given. “RS” denotes reduced shear, and “MB” denotes magnification bias. The combined effect is labelled “RS+MB”.
