... are used to orient the horizontal components towards the fast and slow shear directions. The separated S 1 and S 2 wavefields are processed to generate PS 1 , PS 2 , S 1 S 1 , and S 2 S 2 corridor stacks. Conventional PP corridor stacks are generated by processing the vertical component. The technique...
