The logging data was recorded by Schlumberger in LIS format. All processing, including first arrival picking and stacking, was performed by Schlumberger during Leg 133. The data was then converted into SEGY format at the Schlumberger processing center.


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).
