Parameters Used to Fit Angular Distributions

Acute P Obtuse P 5-3D-DX 10-3D-DX 5-BJT 10-BJT
A 8.35 ± 0.6 5.58 ± 0.8 64.4 ± 2.2 44.2 ± 3.2 5.98 ± 1.4 18.15 ± 1.9
X0 78.7 ± 1.5 78.9 ± 5.3 60.8 ± 0.1 55.6 ± 0.1 59.8 ± 1.4 56.8 ± 0.4
W 26.1 ± 2.1 40.7 ± 8.8 3.02 ± 0.1 2.4 ± 0.2 18.9 ± 1.9 4.6 ± 0.5

Y = A exp −[(XX0)2/(W)2]. A is the preexponential factor, X0 is the centroid of the distribution, and W SQRT [ln(2)] is the FWHM of the distribution. The units of X0 and W are degrees, and A is a dimensionless number.
