Statistical analysis of the observed coherent events in the minimum variance reference frame for the stream at 0.1 AU (green), and at 0.97 AU (orange). Left panels: PDFs for the minimum (a) and intermediate (b) eigenvalues normalized to the maximum eigenvalue, and for λ_min/λ_int (c). Right panels: PDFs of the angles between the maximum (d), intermediate (e), and minimum (f) variance directions and the local magnetic field.
