Table 1.

Peak to peak distance (in mm) between ground truth and estimated rotor density map from grid catheter with different resolution (3 or 6 mm inter-electrode distance) and distance from the atrial wall.

		Distance from the atrial wall
		0 mm (contact)	5 mm	10 mm	15 mm
Grid resolution	3 mm	1.2 (0.9/1.7/1.9)	5 (0.6/3.9/ 0.5)	8.4 (8.9/3.9/12.4)	11.5 (11.7/9.0/13.8)
	6 mm	11.8 (12.9/15.8/6.6)	10.3 (12.6/6.0/12.3)	12.1 (11.7/6.5/18.2)	16.4 (16.0/18.5/14.6)

Distances are given as average value and individual values for all three excitation patterns (Simulation Inferior/Simulation Posterior/Simulation Roof), for each distance-resolution combination.
