Median radial column density (a) and dust temperature (b) profiles of filament 8. Error bars correspond to the standard deviation of observed values at a given radius. Panel a: red solid line shows the median profile measured in the high-resolution (18.2″) column density map. The background level (at >0.18 pc, ~3 × 10²¹ cm⁻²) is marked with a blue-dashed line. The median FWHM of the filament derived from this column density profile is 0.14 ± 0.03 pc. Panel b: dust temperature, which was measured at the center of the filament, is ~ 13 K, comparedto ~15.5 K for the localbackground cloud at >0.18 pc, which is marked by a blue-dashed line.
