The non-oscillatory part of the 2DES signal was removed by subtracting an overdetermined 2D global model. Dashed lines in the oscillation maps are drawn evenly spaced from the diagonal of the spectrum by the selected modulation frequency. The black horizontal line along the detection axis marks the peak of the fluorescence oscillator-strength spectrum (Fig. 1f).
