The Velocity tab controls how the importer brings in seismic velocities.

You can only bring in a single seismic velocity at a time.

Time Units

Sets the specific format of the time.  Time can either be 1-way or 2-way, and can either be in seconds or milliseconds.

Default Datum

Default Replacement Velocity

Sets the default replacement velocity.  By default, this option is set to 5000.

Make this the ACTIVE Velocity Function

Sets the imported velocity as the “active” function.
