Skeletons of the filamentary network extracted with the FilFinder, color-coded by the centroid velocities of the ¹³CO spectral line.The gray map is the H₂ column density map derived from Herschel continuum map (160–500 μm) in Dewangan et al. (2017). The overlaid green contours display ¹³CO column density distribution of filament S242, ranging from 15 to 90% stepped by 15% of the value (1.5 × 10¹⁶ cm⁻²).
