Extended Data Fig. 2: Demonstration of the reproducibility.

Examples of photoelectron spectra for GDD = 135 fs2 taken before and after acquiring the data shown in Fig. 3a. The weak-field contribution has been removed in both spectra (see main text). Other than that no data processing is applied. Very good agreement between the two spectra is found, even though the chirp settings of the seed laser and thus of the FEL were changed in the range −1127 fs2 to +695 fs2 over the course of several hours between the two measurements.
