1) Rounded Values
2) The following conditions are assumed: target larger than the footprint of the laser beam, perpendicular angle of incidence, visibility 23km, average ambient brightness.
3) Accuracy is the degree of conformity of a measured quantity to its actual (true) value.
4) Precision, also called reproducibility, or repeatability, is the degree to which further measurements show the same result.
5) One sigma @ 150 m range under RIEGL test conditions
