    • If the peak at (formula presented) in the spectral function were a (formula presented) function as expected for a conventional Fermi liquid, the finite resolution would make no effect on the peak position. However, the actual ARPES spectra seem to have a finite peak width (formula presented) at (formula presented) in addition to the broadening due to the energy and angular resolutions, as indicated by the analysis in Sec. III E. Therefore, the ARPES peak due to a band near (formula presented) appears below (formula presented) in the actual spectra

    • As for (formula presented), it is due to the Fermi cutoff and the finite instrumental resolution that a weak spectral peak appears slightly below (formula presented) at (formula presented). In reality, the Fermi-surface crossing for (formula presented) is quite close to the (formula presented) point as discussed in Secs. III A and III C. Therefore, in Fig. 99(b), (formula presented) for (formula presented) is plotted at zero with a relatively large error bar
