1) Construct the slant stack section by transforming the
CMP gather from the

(*t*,*y*,*x*)
domain to the domain
using the transformation,

where

*p*:*slant* *parameter*

*x*:*offset*

*y*:*CMP* *coordinate*

*t*:*traveltime*

2) Sort the data into a constant *p* section.

3) Migrate the constant *p* section by prestack slant stack migration.

4) Sort the data into CMP gathers.

5) Do AVO analysis or stack all the *p* sections to get a migration section.
