BVEL
This program can apply a correctional velocity to a down-hole data set. See BRED 7.0.1 for the same process on surface data. The command line arguments are:
bvel infile vel ifast
infile: =input file name
vel =phase velocity to apply
ifast 0=slow option (fft phase rotation
1=fast option (sample shift)
Example:
bvel twave.seg 500. 1

BVEL: Data flattened on 500 m/s (direct wave in bedrock). Overburden is slower (about 100 m/s). Reflection off top of bedrock shown.
