Table 1

Correlation coefficients of ISCs of each order between two channel signals under two conditions.

ISC order		1	2	3	4	5	6
Correlation coefficient	xnor	0.7035	0.1648	0.6998	0.0869	0.0032	0.0062
	ynor	0.6983	0.1851	0.7045	−0.1065	0.11	−0.0203
	xabn	0.5308	0.6293	0.4658	0.6119	0.0043	−0.0628
	yabn	0.6385	0.6576	0.5345	0.0147	−0.0027	0.0125

The bold value is the maximum value of all ISCs (between the order 1 to 6).
