5.3.6 Inverting Data before Stack – Shear Wave
One method of Shear Wave acquisition is done by hitting one side of a plate and storing
the data, then hitting the opposite side of the plate and storing the data. The second record is
inverted and then the two records are summed to show only the Shear wave energy.
Vscope allows this operation. Store both of the records to the database. Then go to the
database and select the second record. Press “Ctrl I” to invert all of the traces in the selected
record.
After the traces have been inverted, the values in the Calibration column will show
negative numbers.
