a, The contour plot of A(k, ω) at Tc. The green line is a guideline indicating an EDC slice at ∼ kF that is presented in c. b, The contour plot of A(k, Δω) at Tc, where Δω = ϵk/ħ-ω. The gray dashed lines are the cut lines of the MEDCs and the red circles are the peak positions of these lines. The orange line shows the MEDC used in d near kF, with a red star highlighted for the peak position. c, d, The spectral slices along the green (EDC) and the orange (MEDC) lines illustrated in a and b. The solid line in d is the fitting result of the MEDC by equation (20).
