We compare the results for nonmagnetic and magnetic impurities in sign-changed s-wave $\\cos(k_x)\\cdot\\cos(k_y)$ and sign-unchanged $|\\cos(k_x)\\cdot\\cos(k_y)|$ SC states. While the patterns strongly depend on the chosen band structures, the sensitivity of peaks around $(\\pm\\pi,0)$ and $(0,\\pm\\pi)$ wavevectors on magnetic or non-magnetic impurity, and sign change or sign unchanged SC orders is common in two models.
