ToW probabilities as a function of 3D MT geometry

	Angle
Separation	Acute	Normal	Obtuse
0 μm	0.79 (n = 38)	0.93 (n = 59)	0.89 (n = 27)
0.5 μm	0.83 (n = 46)	0.70 (n = 60)	0.80 (n = 40)
1 μm	0.58 (n = 36)	0.46 (n = 95)	0.64 (n = 44)

The distance between MTs (rows) and intersection angle (columns) provide full geometric specification for a MT intersection. The angles and distances are as visually illustrated in Fig. 1B. In each case, the number of measurements is given in parentheses. See Fig. 3B for comparison with modeling results.
