Table 1. Deviations for the examined parameters.

Body bending is given in degree, all other parameters are given in pixels. Max^⋆ represents the values obtained by including outliers whereas OL gives the number of outliers.

Deviations	Mean (±Std)	Median	Min	Max	Max⋆	OL
Center of mass	1.86 (±0.23)	1.85	1.21	2.55	2.84	17 (0.80%)
Central spine point	1.84 (±1.10)	1.57	0.50	4.58	16.84	61 (2.89%)
Body bending	3.54 (±7.51)	2.55	0.00	13.16	171.00	46 (2.18%)
