(a) Laplacian of the ARPES intensity plot measured at incident photon energy values of 392, 405, 418, 431, 444, 457, and 470 eV. (b) MDCs at EB = 0 eV in the ARPES intensity maps. The results of the spectral fittings of the MDCs are also shown. In the fitting procedure, a Lorentzian function and constant background are used. Each pair of peaks is constrained to have the peak position symmetrical with respect to kx = 0 and an equivalent full width at the half maximum. The open circles are experimental data; black lines are the fitting result; and blue, green, and red lines are the components used for the fittings.
