1. Relative Displacement is the difference between the displacement of the center of mass and the table displacement = Block Disp - Table Disp

2. PGA: Peak Ground (Table) Acceleration

3. PGD: Peak Ground (Table) Displacement

4. Peak Relative Displacement assuming zero residual displacement at the beginning of the run

5. Cumulative Residual Relative Displacement at the end of the run

6. The shear force is estimated as the mass of the block times the acceleration at the center of the block, ignoring damping forces

7. Base moment is estimated using Newton's second law accounting for translational and rotational inertia forces and ignoring damping forces

8. Long: Measurements in the longitudinal direction

9. Lat: Measurements in the lateral direction
