(a) XTG data obtained by scanning Δtopt at ΔtFF = 0; the rise time of the signal can be associated with the FEL–optical cross correlation while the decay is related to some specific sample dynamics. (b) XTG data obtained by scanning ΔtFF at Δtopt = 0, that can be associated with the FEL autocorrelation. Red, blue and green curves are Gaussian functions with FWHM of 330 fs, 70 fs and 150 fs, respectively, where the latter is representative of the optical pulse duration.
