This is a local Cartesian coordinate system. The R, Theta and Phi axes are oriented relative to a MAGSAT magnetic field model (Langel et al., 1980) positive in the directions of increasing radial distance from the center of the Earth (i.e., outward), increasing magnetic colatitude (i.e., southward) and increasing azimuth angle (i.e., magnetic east).
