Migration

1) Copy the migration flow as in previous exercises.

2) Click (MB2) on migration velocity analysisto open parameters box. You can change the velocities by clicking (MB1) on the velocityvalues already listed. Once you have specified the velocities to be applied, exitthe parameters box and click Execute (MB2).

3) Once the flow has run successfully, the followingwindow will come up:

4) To view the results of each velocity value,click on the arrow icon and save each screen (as in the Bandpass filter excercise).Then scroll through the results and decide which velocity works best. You can goback and specify new velocities with a narrower range to refine the output.
