Upper panels: maps of $\mathcal{R}$, ${\mathcal{R}}^{\mathcal{A}}$, $\mathrm{\Delta }{\mathcal{R}}^{\mathcal{A}}$ from 3$\times$3 cliques and bipolar voltage maps $V^{b\text{-}x}$, $V^{b\text{-}y}$, $V^{b\text{-}m}$, for $\mathrm{\Psi }$ = ${45}^{\circ }$, performed assuming a variable electrode-to-tissue distance and noise free ((a) and (b)) and noisy ((c) and (d), with noise level ${\sigma }_v$ = 46.4 $\mu V$) u-EGMs. Lower panels: detected fibrotic areas (brown), using the thresholds that maximize detection accuracy of each map
