*		Peak motions in uncorrected acceleration are considered reliable.  However, distortions in the signal frequencies introduced by uneven film transport, particularly near the times of the highest accelerations (near 2 and 2.2 sec) produce severe offsets in velocity and displacement such that these derived time series and the response spectra are considered unreliable. PGA values listed are uncorrected acceleration.
