Table 1.

Average Bias Values for Each of the Drawn Discs, Standard Deviation (SD), and Relative Root Mean Square Error (RRMSE) Calculated for the Drawn Discs’ Parameters (Width and Height) in Each Displayed Position Compared With the Value of the Physical Discs in the Apparatus (Diameter = 75 mm).

	Above width of drawn discs	Above height of drawn discs	Below width of drawn discs	Below height of drawn discs
Bias	−0.16	−0.29	−0.19	−0.29
SD	15.14	12.90	14.49	10.47
RRMSE	3.51	3.03	3.46	1.99
	Left width of drawn discs	Left height of drawn discs	Right width of drawn discs	Right height of drawn discs
Bias	−0.24	−0.18	−0.25	−0.16
SD	12.04	12.32	12.22	13.82
RRMSE	2.47	2.40	2.59	2.97

RRMSE = Relative Root Mean Square Error.
