Configuring the Semblance

  1. From the Velocity Picking window, open the Semblance tab.
  2. Define the Window Length (ms) and the Offset weighting power of the semblance.
  3. In the following sections, you can adjust the extents and increments of the TWT (ms) and Velocity (m/s) to be considered when generating the semblance. If you have chosen to pick eta, the η Semblance extents and increment will be available to configure.

Tip: To change the colour of the semblance in the Semblance View, see Editing a Colourbar.
