was significantly lower with the 1-1 pair compared to RR and other pairs. This finding aligns with the joint plot of 𝜀 𝛾 and 𝜀 𝜕𝛾 (Figure ) and the 𝜀 𝛾 violin plot (Figure (c)). Figure shows the DRTs recovered using the 1-1 pair and RR (with optimal λ); the 1-1 pair eliminated oscillations evident in the RR-recovered DRT. Furthermore, the average impedance recovered with the 1-1 pair closely approximated the exact impedance for the distant 2×ZARC model (Figure and average impedance error 𝜀̅ 𝑍 = 9.04 × 10 -1 Ω). These preliminary results strongly suggest that the 1-1 pair outperforms RR and all other considered pairs for an optimal 𝑳-matrix choice (Section 3.1.2). Subsequent analysis will, therefore, focus primarily on the 1-1 pair, which will be compared to RR.
