Dispersion of Magnetic Fields in Molecular Clouds. I
We describe a method for determining the dispersion of magnetic field vectors
about large-scale fields in turbulent molecular clouds. The method is designed
to avoid inaccurate estimates of magnetohydrodynamic or turbulent dispersion -
and help avoiding inaccurate estimates of field strengths - due to large-scale,
non-turbulent field structure when using the well-known method of Chandrasekhar
and Fermi. Our method also provides accurate, independent estimates of the
turbulent to large-scale magnetic field strength ratio. We discuss applications
to the molecular clouds OMC-1, M17, and DR21(Main).Comment: 19 pages, 2 figures, 1 table, accepted for publication in the Ap
