a Director profiles of DWs pairs for ω = 0.1 and different elastic ratios K1/K3. b The width parameter Lπ vs K1/K3 for different anchoring anisotropies ω. c Ratio of width parameters L3π/2/Lπ/2 vs K1/K3 for different anchoring anisotropies ω; the dashed line shows L3π/2/Lπ/2 = 1.8 obtained by averaging experimental data for 64 DW pairs.
