Our evaluation of the lattice-induced light shift, the density shift, and the second-order Zeeman shift is based on an interleaved measurement where we measure the frequency shift using the alternating stabilization of a clock laser to the $\\mathrm{6s^{2}\\,^{1}S_{0}-6s6p\\,^{3}P_{0}}$ clock transition with two different experimental parameters.
