The logging data was recorded by Schlumberger in DLIS format. All processing, including first arrival picking and stacking, was performed by Schlumberger during Leg 206. The data was then converted into SEGY format at the Borehole Research Group of the Lamont-Doherty Earth Observatory, using the SEGY Save module in GeoFrame.
Stacks are generally calculated with at least seven good traces.
All the data in the SEGY files are sorted shot by shot (i.e. chronologically).
