Corrections to “Negation Invariant Representations of 3-D Vectors for Deep Learning Models Applied to Fault Geometry Mapping in 3-D Seismic Reflection Data”

In the above article
[1]
,
(22)
should be corrected by inserting
$\sqrt{3}$
into the denominator of the last term in the first line as follows:
\begin{align*}&w_a=1-\frac{\lambda_b}{2}-\frac{\lambda_c}{2}=1-\frac{x}{2}-\frac{y}{2 \sqrt{3}} \\& w_b=1-\frac{\lambda_a}{2}-\frac{\lambda_c}{2}=\frac{x}{2}-\frac{y}{2 \sqrt{3}} \\& w_c=1-\frac{\lambda_a}{2}-\frac{\lambda_b}{2}=\frac{y}{\sqrt{3}}(22).\end{align*}
