Experimental measurements of $C_{\upsilon }^{\left(\delta \right)}\left(\tau \right)/C_{\upsilon }^{\left(\delta \right)}\left(\tau =0\right)$ for chromosomal loci in the (A and B) preconfined (C and D) crossover and (E and F) confined regimes. In panels A, C, and E, $C_{\upsilon }^{\left(\delta \right)}\left(\tau \right)/C_{\upsilon }^{\left(\delta \right)}\left(\tau =0\right)$ is plotted against time-lag τ. In panels B, D, and F, the time-lag has been rescaled by δ. Colors (blue to red) represent different values of δ: (A and B) 1–50 s, at 1 s intervals; (C and D) 20–1000 s, at 20 s intervals; and (E and F) 600–13,800 s, at 600 s intervals. (Solid black lines in B, D, and F are the analytical theory for an fLm process with α = 0.4.) C_υ in panels A and B was calculated along both axes of untreated cells; in panels C–F, it was calculated along the width (y) axis of untreated (C and D) or rifampin-treated (E and F) cells.
