Table 2.

Thresholds used to classify phase patterns.

Phase pattern	Thresholds
planar wave	σg(t) < θ3
radial	$|R_{\parallel }|>{\theta }_8$
synchronized	σp(t) < θ1, and σg(t) ≥ θ4
circular	σp(t) ≥ θ2, σg(t) ≥ θ4,
	C(t) ≥ θ6 and |R⊥| ≥ θ7
random	σp(t) ≥ θ2, σg(t) ≥ θ4,
	and μc(t) ≤ θ5

A time point was classified as one of the 5 listed phase patterns if all corresponding threshold criteria were met. Tests were administered in the order given by the table, and the first match is chosen as the classification.
