Linear Forcefree Magnetic Fields for Solar Extrapolation and Interpretation
Abstract
This paper discusses the interconnection of the various linear forcefree magnetic field formulations, the specific phenomenological and topological parameters of these formulations, and their usefulness. Particularly, the limitations and usefulness of linear forcefree fields are discussed. Specific field configurations are related to magnetographic interpretation. The relationship of the integral and Fourier procedures is shown explicitly. The physical interpretation of linear forcefree fields is shown by analytic models and from the Marshall Space Flight Center solar vector magnetograms.
