Magnetic filling factor α maps for snapshots A (left panels), B (middle panels), and C (right panels). Panels a–c show α calculated using actual field (i.e. using Formula (1) and MHD data), panels d–f, g–i, and j–l show α calculated using the MLR method (Eq. (6)), Stokes V width method (Eq. (7)), and statistical method (Eq. (8)), respectively. Magnetic filling factor values in pixels with magnetic field |B| < 100 G are ignored.
