Orientation of the Gaussian ellipsoid characterizing our idealization of magnetized turbulence in the ( v ₁, v ₂, u) coordinate system. The v ₁ and v ₂ axes define the plane of the sky, while the line of sight points along the negative u-axis. The inclination angle relative to the line of sight of the ellipsoid symmetry axis (and of B ₀) is given by α, while the angle β defines the orientation of its projection on the plane of the sky.
