Figure 3a:

The folder "Figure03a" contains the data for Figure 3a in .csv format. 

The real absorptive 2D spectra are provided in the files "Figure3a_data_T=20fs_D=20fs.csv", "Figure3a_data_T=20fs_D=500fs.csv", "Figure3a_data_T=500fs_D=20fs.csv", and "Figure3a_data_T=500fs_D=500fs.csv". 
Each 2D spectrum is stored in a matrix in which the first dimension (rows) corresponds to the excitation axis while the second dimension (columns) corresponds to the detection axis. The value after "T" in each file name specifies the delay time between the second and third excitation pulses (T), in units of femtoseconds (fs). The value after the "D" in each file name specifies the delay time between the fourth pulse and the fifth (ionization) pulse (Δ), in units of femtoseconds (fs). All 2D spectra are normalized to the global absolute maximum across all four 2D spectra.
The excitation and detection energy axes are provided in the files "Figure3a_wtau.csv" and "Figure3a_wt.csv", respectively, in units of electronvolts (eV).

Spectral positions of the regions of interest investigated in Figures 3b and 3c:

Name	excitation axis	(eV)	detection axis (eV)
DP1	1.6911–1.7632 		1.6911–1.7632 
DP2	1.8568–1.9289		1.8568–1.9289
CP1	1.6911–1.7632 		1.8568–1.9289
CP2	1.8568–1.9289		1.6911–1.7632

Figure 3b:

The folder "Figure03b" contains the data for Figure 3b in .csv format. 

The file "Figure3b_data_T_dependency_D20fs.csv" contains the integrated signals of the regions of interest (ROIs), as specified in the first row of the file and indicated in the 2D spectrum shown in Figure 3a.

The delay time between the fourth pulse and the fifth (ionization) pulse (Δ) is fixed at 20 fs. The delay time between the second and third pulses (T) is provided in the first column of "Figure3b_data_T_dependency_D20fs.csv". All data is normalized to the global absolute maximum accross all ROIs. The file "Figure3b_fit_T_dependency_D20fs.csv" contains the results of monoexponential fits to the ROI signals "DP2" and "CP2" provided in "Figure3b_data_T_dependency_D20fs.csv". The delay time T is again provided in the first column. Data points with delay times T<150 fs are excluded from the fitting procedure.

Column delimiter: semicolon.


Figure 3c:

The folder "Figure03c" contains the data for Figure 3c in .csv format. 

The file "Figure3c_data_Delta_dependency_T20fs.csv" contains the integrated signals of the regions of interest (ROIs), as specified in the first row and indicated in the 2D spectrum shown in Figure 3a.

The delay time between the second pulse and third pulse (T) is fixed at 20 fs. The delay time between the fourth pulse and fifth (ionization) pulse (Δ) is provided in the first column of "Figure3c_data_Delta_dependency_T20fs.csv". All data are normalized to the global absolute maximum across all ROIs. The file "Figure3c_fit_Delta_dependency_T20fs.csv" contains the results of monoexponential fits to all ROI signals provided in "Figure3c_data_Delta_dependency_T20fs.csv". The delay time Δ is again given in the first column. Data points with delay times Δ<30 fs are excluded from the fitting procedure.
