Properties

Name	Type	Description
timestamp	object	Timestamp of scan
frame_id	string	Frame of reference
pose	object	Origin of scan relative to frame of reference; points are positioned in the x-y plane relative to this origin; angles are interpreted as counterclockwise rotations around the z axis with 0 rad being i
start_angle	number	Bearing of first point, in radians
end_angle	number	Bearing of last point, in radians
ranges	array	Distance of detections from origin; assumed to be at equally-spaced angles between `start_angle` and `end_angle`
intensities	array	Intensity of detections
