    • The influence of the exciton at 2.395 eV (X′): The G-X′ coupling should give the blue shift contribution. While, the X-XX′ coupling, where XX′ represent biexcitons which consist of X and X′, may give the red shift contribution. We also tried to include these contributions and found that the oscillator strength of X′ is not strong enough to compensate for the rest of discrepancy and that the fit becomes worse in the range around 2.30 eV.

    • Peak energies were determined by spectral fitting with the Gaussian function with the following rule: the peak energy should locate at the center of the fitting range of 4 meV.

    • At 2.30 eV with higher intensity, we observe the splitting of the band. With low intensity, however, two split peaks are not resolved owing to linewidths. We retrieved the peak energy of this convoluted spectrum.

    • We diagonalized the model Hamiltonian to determine the energy and intensity of transitions. Then, a spectrum was calculated on the assumption that all transitions have Gaussian linewidths of σ=7 meV. The pump light was assumed to be monochromatic. Obtained spectra were used for determining the peak energies, in the same way as experimentally observed spectra.
