Singular value decomposition of the blank-corrected scattering data for cytochrome c. Experimental conditions are the same as in Fig. 4. Only the first three basis vectors along the scattering angle and the time axis are shown. The remaining vectors consist of random noise as judged by their autocorrelations and singular values. The data are fit to a double exponential function with time constants of 30.2 and 457 µs.
