Notes. Columns: (2) total number of filaments in each field (same as Col. 5 of Table 2). (3) Fraction of subcritical filaments with , i.e., in each field. (4) Fraction of transcritical filaments with , i.e., . (5) Fraction of supercriticalfilaments with , i.e., . (6) Total gas mass of extracted filaments in each cloud, where the mass of a filament of length lfil was estimated as . (7) Fraction of cloud mass in the form of filaments, , where is given in Col. 5 of Table 1. (8) Fraction of dense gas mass ( cm−2) in the form of filaments, . To estimate , a mask corresponding to 0.1 pc-wide filaments was first constructed from the DisPerSE skeleton derived in each region. was then computed within this filament mask from the corresponding column density map. corresponds to the product of Cols. 6 and 7 in Table 1. (9) Area filling factor of the entire sample of extracted filaments in each field, , where the area of a filament was estimated as Afil = 2hr × lfil and is given in Col. 5 of Table 1.
