First panel: f vs. β for law 1 (stars), law 2 (diamonds), and law 3 (triangles). Second panel: same for f′ vs. β. Third panel: same for chi2 vs. β. Fourth panel: same for δS_QS in 1′ × 3′ quiet box variability (%) vs. β. The horizontal lines highlight the 1 and 2% levels constrained by Kitt Peak observations. Fifth panel: δH (in units used by Rezaei et al. (2007), normalized to match the results from Harvey et al, 1999, at 100 G) vs. β. The horizontal lines highlight H values of 1 and 2, compatible with observations from (Rezaei et al. 2007). Sixth panel: same for a normalization at 30 G.
