In 2-D, ADCIGs are computed by applying a slant-stack decomposition to the prestack image
along the subsurface-offset axis at a constant midpoint. The kinematics of the transformation
to the angle domain are defined by the following change of variable:
| ![\begin{eqnarray}
\widehat{\gamma}
&=&
\arctan
\left.
\frac{\partial z_\xi}{\part...
...i},
\\ z_{\widehat{\gamma}}
&=&
z_\xi-h_\xi
\tan \widehat{\gamma},\end{eqnarray}](img7.gif) |

where
is the depth of the image point after the
transformation.
