Notes. Table columns: total mass M, effective radius Reff, column density NH2, number density nH2, non-thermal velocity dispersion ΔVNT, corrected non-thermal velocity dispersion ΔVNT*$\Delta V^*_{\rm NT}$, position angle of major axis ϕPA, circular mean of the magnetic held orientations ϕB, circular angular dispersion of the magnetic held orientations σϕ, ratio of turbulent to large-scale magnetic held components Bt2B02$\frac{\langle B_t^2 \rangle}{\langle B_0^2 \rangle}$, plane-of-sky magnetic held strength BPOS, gravitational energy density uG, magnetic held pressure PB, and turbulent pressure PT. The uncertainties of M and NH2, related quantities are propagated from the errors of the measured intensity, temperature and dust opacity as described in Section 4.2.(a) Line-width from NH3 (1.1) line (Lu et al. 2014). (b)Due to the lack of a large enough number of polarization segments and the uniformity of the magnetic held within these clumps, the best-fit of structure function failed. (c)Note the angular dispersion of the magnetic held orientation for SDC18-N-1 and SDC18-N-3 are calculated using polarization segments outside of the defined core boundaries (see Section 4.2).
