Classification rules of the RCGD algorithm. Refer to Section 4.2 for more details on the thresholds.

Class	Parameters of the Regression Model
	SEth = 400 dB2, ΔPth = 3 dB
	Pth = 68 dB, ΔRth = 6 m
	SE	ΔP	P	ΔR
Ground (all conditions must be verified)	< SEth	< ΔPth	<Pth	> ΔRth
Non-ground (one condition must be verified)	≥ SEth	≥ Δ Pth	≥ Pth	≤ Rth
