Extended Data Figure 1: Comparison of the TRXSS signals at SACLA and KEK and the TRXSS data in the entire time range.
From: Direct observation of bond formation in solution with femtosecond X-ray scattering

a, Comparison of the difference scattering curves at 100 ps time delay measured at SACLA (black) and KEK (red). The error bar at each data point indicates the standard error determined from 50 independent measurements. The two curves are nearly identical to each other within the experimental error, indicating that the difference scattering curves are highly reproducible and independent of the facility. b, Experimental difference scattering curves, qΔS(q, t), in the entire time range from –800 fs to 1 μs.
