The momentum distribution curves (MDC) were fitted at each energy $\\w$ employing the SC Green's function along several cuts perpendicular to the Fermi surface with the tilt angle $\\theta$ with respect to the nodal cut. The clear observation of particle-hole mixing was utilized such that the complex self-energy as a function of $\\omega$ is directly obtained from the fitting.
