Figure 5

Figure shows the histograms for the scaled-thermal fluctuations averaged in space after the system has reached a steady-state. The top panel shows the distributions for \({l}_{z}=4.74\,mm\) and the bottom panel for \({l}_{z}=5.02\,mm\). Panels (a and c) plots the scaled-fluctuation frequency counts for the patterned region, P with a kernel density estimate (dashed). Panels (b and d) plot the scaled-fluctuation frequency counts for the non-patterned annular region, R with a normal curve fit centered at zero (solid).
