Lithoprobe Data Archive DLT tape listing
GLIMPCE LF: Shot gathers
The shots spill over from tape to tape. The numbers after the
dots in the FFID column indicate the leading/trailing trace number. The tapes
arrived in rough shape, are very sticky, and did not always copy as single
files to 8mm tapes. The numbers in the COMMENTS column indicate how many
records (headers + traces) came off. Line AA is line A reshot, etc.
Several input tapes to the 8mm tapes are bad, check the LF listing.

In the following entries, stdvel stands for 5750 m/s at t=0, 6250 m/s at t=20.
bestvel stands for 'best smooth velocity model'; (details follow in parentheses).
velfilt stands for velocity filtering with a taper of 3 - 3.9 km/s.
stdproc stands for AGC, bandpass filtering 7-9-35-40 Hz, plus 'velfilt' followed by 'bestvel' fk migration
