The biexciton is fitted with a Lorentzian (red dash-dotted line). X2 is not fully Lorentzian and is best approximated by a Voigt function (green dash-dotted line), hinting at the underlying presence of X1 whose impact remains however negligible. The resulting two-peak fit is highlighted with a blue dash-dotted line. The detection window of the HBT setup is indicated along with the contribution of X2 (IX2) and XX (IXX) to the measured signal (hatched areas). Itot,X2 stands for the integrated intensity of the X2 line. The FWHM of X2 is highlighted
