Plots of estimated length l_fil against massper unit length (panel A), column density contrast C⁰ against background column density (panel B), deconvolved half-power diameter hd_dec against (panel C), and outer diameter (2R_out) against C⁰, for the entire sample of 1310 extracted filaments (panel D). Panel B: horizontal line corresponds to C⁰ = 0.3, the minimum contrast imposed as a selection criterion in Sect. 3.5. Panel c: distribution of measured hd_dec values has a mean of 0.11 pc, a standard deviation of 0.06 pc, a median of 0.10 pc, and an interquartile range of 0.08 pc.
