There are 24 traces in each CSG. The offset interval is 25 ft. The minimum offset is 25 ft. The offsets for trace 1,2, ..., 24 are 25ft, 50 ft, ..., 600 ft.

The sample interval is 0.25 ms. Total sample nummber is 4000. The recording length is 1 s.

Only the bandpass filter has been applied to data (50-60-450-560 Hz).

The sonic data is written out as a file: reflectivity.mat. The unit is depth. The depth2.mat contains the coordinators for plot
