Illustration of a detected and measured filament in a high-resolution surface density image at 11.7″. Left: skeletons of the detected filaments with a contrast C > 0.5 is shown by the white curves and the black curve is the skeleton of a filament whose measured radial profile is shown in the right panel. Right: median one-sided surface density profiles measured on the two sides of the filament (blue and purple solid lines). The black dashed curve shows the beam profile. The median half maximum width of the filament is 0.33 ± 0.19 pc.
