Extracted cores and filaments in the Vela C molecular cloud on the 11.7″-resolution surface density image. The locations and sizes of the cores are measured from the surface density map. The black, green, and blue ellipses represent the 329 prestellar cores, 84 unbound starless cores, and 149 protostellar cores, respectively. The full axis of the ellipses is two times the Gaussian full width at half maximum (FWHM). Filamentary networks are shown by the global scale-independent skeletons of the filamentary structure. The filament linear density Λ^W in each point along the skeletons was estimated from Eq. (7) assuming a width of W = 0.3 pc (Fig. 11).
