Shape and size parameters.

Parameter	Types A and B	Type C	Type D
$a_{1t}$ (mm)	$\mathrm{TN}(59.70,3.58,50.77,71.5)$		$\mathrm{TN}(50.05,3.58,42.9,57.2)$
$a_{1b}/a_{1t}$	$N(1,0.02)$
$a_{2r}/a_{1t}$	$N(1,0.05)$
$a_{2l}/a_{2r}$	$N(1,0.05)$
$a_3/a_{1t}$	$\mathrm{TN}(0.85,0.14,0.8,1.2)$	$\mathrm{TN}(0.85,0.12,0.7,1.1)$	$\mathrm{TN}(0.85,0.1,0.7,1.1)$
${ϵ}_1$	$N(1,0.1)$
$B_0$	$\mathrm{TN}(0,0.1,-0.18,0.18)$
$B_1$	$\mathrm{TN}(0,0.1,-0.18,0.18)$
$H_0$	$\mathrm{TN}(0,0.15,-0.11,0.11)$
$H_1$	$\mathrm{TN}(0,0.25,-0.3,0.3)$

$N(\mu ,\sigma )$: Gaussian distribution with mean $\mu$ and standard deviation $\sigma$.

$TN(\mu ,\sigma ,a,b)$: truncated Gaussian distribution in interval $(a,b)$.

For hemispherical shapes ($a_{1t}=a_{1b}=a_{2r}=a_{2l}=a_3$), the ${ϵ}_1$ value is set to “1,” and the $B_0$, $B_1$, $H_0$, and $H_1$ values are set to “0.”
