Site 4 SASW test

SASW tests at site 4 to obtain shear wave velocity profile for the 3D profiling inversion. Tests utilized the 3 geophones placed during the 3D profiling test. Sensor spacing of 60, 30, 18, 9, 6, 3, 2and 1 m are used in the SASW tests. Stepped-sine function provided by Quattro analyzer is used to drive T-Rex for the SASW tests. The final units used in analysis are the ratio V/V, which are the units provided in columns 2 through 5 in the Unprocessed Data files. The units in column 1 are Hertz.
