===== Algorithm =====

**Search Radius 2D**\\
The 2D search radius around the user coordinates to get the antenna.

**Search Radius Z**\\
The Z radius around the user coordinates to get the antenna. 

**Z Slice Size**\\
The height of the horizontal slices used to detect the antenna. 

**Proximity Distance**\\
The proximity distance used for clustering of slice points. 

**Profile Outline Step**\\
The step used to create the profile outline of the first slice of points.

**Reposition Step**\\
The step used to reposition the profile to best match the different slices of the antenna.

**Reposition Step Max**\\
The maximum step to reposition the profile to match a horizontal slice of points. This distance also limits the maximum inclination of an antenna.

**Outline Match Percent Min**\\
The minimum match percentage of the antenna profile to a slice of points. 

===== Output =====

**Get pointcloud selection**: enables creating a pointcloud selection file with the detected feature.
