Understand the principles of EOM.

Know that EOM is based on prestack Kirchhoff migration.

Know that EOM is a time and depth migration.

Know the definition of equivalent offset.

Understand how CSP gathers are formed.

Know that CSP gathers are formed with no time shifting of the input data.

Know that CSP gathers may be formed at random locations:

Understand the principles of Kirchhoff MO.

Know that CSP gathers are formed with slight dependence on velocity, but provide accurate velocities after they are formed.

Know that principles of EOM may be extended to rugged topography, converted-wave processing, vertical array data, and may be used to extract residual statics.
