Distributions of (black) and (red) widthsderived from individual profiles along and on either side of the crests for the selected sample of 599 filaments. The median and values are 0.09 and 0.11 pc, respectively, and the interquartile range is 0.11 pc for both distributions. The black and red curves show power-law fits to the tails of the and distributions, respectively (ΔN∕ΔW ∝ W^−2.6±0.5, for both distributions). For comparison, the distribution of Jeans lengths, , is also shown (blue histogram, cf. Fig. 7).
