M3C2- Export normals of cylinders

[GiadaPos]

Hello,
I run M3C2 for multi temporal comparison, then I exported the txt file of the result.
The file contains several columns:
X Y Z normal scale significant change distance uncertainty M3C2 distance Nx Ny Nz

What Nx, Ny, Nz are about?
Are they the normal of the cylinder calculated during M3C2 comparison? Or are they referred to the the original point cloud?

Thank you for the answer,
Giada

Normally Nx, Ny, Nz should simply be the normals of the (core) points. And it's indeed the directions of the cylinders.
