Profile Picture
Z0.8 (m) 0.0

Z0.8 is the depth where the average of the profiles reach the velocity of 0.8 km/s

Z1 (m) 0.0

Z1 is the depth where the average of the profiles reach the velocity of 1 km/s,

Z1.5 (m) 0.0

Z1.5 is the depth where the average of the profiles reach the velocity of 1.5km/s
