Notes. The crests 1 to 4 trace the ridge. The crests 5 to 14 correspond to the sub-filaments, for which in and out values are given (see Figs. 13–15). See Sect. 4.1.2 for the calculation of the parameters and Sect. 4.1.2 for the definition of the in and out parts of the sub-filaments. The values given in this table are derived from BISTRO observations at a spatial resolution of 14′′. These values are calculated along the ridge crests (crests 1 to 4) and toward one-third of the “in” and “out” parts of the sub-filaments (cf., Sect. 4). The row “1 to 4” corresponds to the full length of the ridge combining the crests 1 to 4, hence the crest 4, which is the longest, contributes the most to these values. The last two rows “median in” and “median out” give the median values measured toward the sub-filaments “in” and “out” parts, respectively (see Fig. 13). Columns: (1) Crest number. (2) Column density calculated from the total intensity Stokes I850 for T = 20 K (see Sect. 2.3). (3) Volume density estimated from the values for a filament width of Wfil = 0.11 ± 0.04 pc (cf., André et al. 2016). (4) Mass per unit length calculated using the relation: Mline = Σ × Wfil, where is the gas surface density, Wfil = 0.11 pc, the mean molecular weight per hydrogen molecule, and mH the mass of a hydrogen atom. (5) Total velocity dispersion estimated using the relation suggested by Arzoumanian et al. (2013) rescaled to T = 20 K. (6) Virial mass per unit length , where σv is the total (turbulent and thermal) velocity dispersion (Col 5) and G is the gravitational constant. (7) Plane-of-the-sky B-field strength BPOS calculated using Eq. (5). (8) Magnetic critical mass per unit length calculated using Eq. (6). (9) Effective virial mass per unit length, taking into account the kinetic (thermal and turbulent) and B-field support: . (10) Thermal stability parameter (defined as the inverse of the fcyl parameter discussed in Fischera & Martin 2012; Arzoumanian et al. 2019), with . (11) Virial parameter . (12) Magnetic virial parameter . (13) Effective virial parameter, taking into account the kinetic and magnetic support, .
