Different survey geometries give different resolution limits of migrated images, but limitations on paper length restricted our range of examples. Equation (18) in our original paper applies to a fixed source and receiver distribution, such as the one performed by Morey and Schuster (1999) in their 3-D imaging experiment. However, Tabti et al.’s request for the moving array formula is excellent, so the derivation is given below for a moving receiver array.
