Each data point represents a single shot. The range markers indicate the first and third quartile of the wavelength distribution at different pump-probe delays Δt. The dotted lines represent the best fits to the filament merging model according to Eq. (1). The average error and standard deviation of the distributions (not shown in the figure) are 0.15 μm and 0.02 μm for the copper measurements and 0.19 μm and 0.06 μm for aluminum, respectively.
