ACFs and CCFs obtained from filtering of the intensity trace at the middle point. Particle number-corrected ACFs of the 4-ns, 3-ns component (black curves 1, 2), amplitude-corrected CCFs, 3 × 4 ns, 4 × 3 ns (red curves 1, 2); particle number-corrected ACFs of the free and condensed DNA measured separately (blue curves 1, 2). (Inset) ACFs and CCFs (not corrected) obtained from filtering of the intensity trace at the middle point. ACFs of the 4-ns, 3-ns component (black curves 1′, 2′), and CCFs, 3 × 4 ns, 4 × 3 ns (red curves 1′, 2′).
