where ©m/„ is the correlation angle between Lm and Ln. Note that for 0 = 90 deg, the previous result is recovered.

Because Lm and Ln are not orthogonal, the x and y components are not independent. A measure of the degree of their interdependence is the correlation coefficient, Cxy, given by (Eq. (1 l-27d))
