LASA data

Several years ago I visited Albuquerque Seismological Laboratory and spun numerous 9-track tapes. My reward was recordings of about 150 earthquakes captured by the LASA array. What follows is a list of the events I recovered. The data can be downloaded in SAC format from the ASL ftp site ftp://aslftp.cr.usgs.gov/pub/LASA. I'm currently using this data to study inner-core scattering using observations following PKIKP and lower-mantle/CMB scattering using scattered PKKP waves. I would appreciate your profesional courtesy by leaving these topics for me.

tdif == (start time) - (origin time)
tend == (end time) - (origin time)

Note, several events have significant data gaps or bad data between tdif and tend.
