4.5.3 Dip Angle

The dip angle attribute converts the apparent dip (slowness-us/m) into degrees. It calculates the true dip from the apparent dip (slowness). If no velocity model is available, specify a constant velocity in the velocity field. The velocity should be given in meters per second (m/s).

The dip angle is calculated as follow.

where TWT-dip is in micro seconds per meter and Z-dip is in millimeters per meter.

OpendTect uses SI-unit systems.
