+I am grateful to Tomas Straupis, who handed me the {\WM}\cite{wang1998line}
+paper in a warm pre-COVID summer evening. I got intrigued. He was also an early
+beta-tester of my implementation, and helped me understand where the initial

+Many thanks to NŽT for providing the datasets with a very permissive license.
