    • The Gaussian-like peak is superimposed by a very weak, energy independent SN background. The very weak background results from the ensemble of about 30 QDs in the laser focus, which have a large detuning and consequently contribute extremely weakly.

    • The absorption probability of the single QD on resonance amounts to (Equation presented). The intrinsic spin relaxation rate at (Equation presented) and zero intensity is set to (Equation presented) but any value well below 2 kHz does not significantly change the depicted calculations. The radiative lifetime (Equation presented) is set to 1 ns. The detuning of the three QD configurations in units of the QD homogeneous radiative linewidth are 2.6, 11.9, and 55.3. The respective quantifiers (Equation presented) are 1.08, 0.89, and 1.12.

    • In detail, the line shape of the SN spectrum is always a convolution of several Lorentzians which modifies especially the tail of the spectrum. This modification is most significantly in the intensity regimes, where the dominant QD configuration changes.
