There is a remarkable relationship between the amplitude of a
discontinuity
on zero-offset migrated sections and the amplitude of the corresponding
discontinuity on a CSP section for the point *R* that belongs to the
same normal ray:
This means that we can use the formulas for CSP patterns at s=r; the
constant factor of 4 doesn't play any role. If we take into account the
equality
we receive
and
The operator is not unique. If the
medium is homogeneous then there is a whole family of operators
that acts according to the formula:

and
In the 2D case the amplitude of the image depends on the radius of
transverse curvature of the reflector. But if the reflector is planar
or cylindrical, we have a family of true-amplitude operators of the
same type as
