Mean values of the differences between the original physical parameters and the inferred values (ΔX_i; circles) and standard deviations around the mean (dashed lines; σ_x): (panel-a)) ΔB_∥ and σ_B∥ as a function of B_∥; (panel-b)) ΔB_⊥ and σ_B⊥ as a function of B_⊥; (panel-c)) ΔB and σ_B and a function of B; (panel-d)) Δγ and σ_γ as a function of γ; (panel-e)) Δφ and σ_φ as a function of γ; and finally, (panel-f)) Δα and σ_α as a function of α. Blue shows the results obtained from a photon-noise level of σ = 10^-3 and selection criterion S/R_quv (from Fig. 1); red represents σ = 3 × 10^-4 and S/R_quv (from Fig. 2); green is for σ = 10^-3 and S/R_qu (from Fig. 3); and yellow is for σ = 3 × 10^-4 and S/R_qu (from Fig. 4).
