Measurement error description. SD: standard deviation.

	Magnification	Mean error in mm (SD)	Median error in mm [min-max]	% of measurements with a null error
K-low	1.9 : 1	−0.02 (0.16)	0.00 [−0.30; 0.20]	5/24 (20.8%)
K-medium	3.4 : 1	0.02 (0.07)	0.00 [−0.10; 0.20]	14/24 (58.3%)
W-low	1.9 : 1	0.05 (0.13)	0.10 [−0.10; 0.30]	4/24 (16.7%)
W-medium	3.4 : 1	0.04 (0.06)	0.00 [−0.10; 0.20]	14/24 (58.3%)
W-high	10 : 1	0.03 (0.06)	0.00 [−0.10; 0.10]	14/24 (58.3%)
O-low	1.9 : 1	−0.13 (0.13)	−0.10 [−0.30; 0.20]	7/24 (29.2%)
