Abstract
We generalize imaging conditions and angle decompositions for wave-equation migration of primary and converted waves. Prestack images are described as functions of space-shifts or time-shifts between source and receiver wavefields at every image location. Angle transformations allow construction of common-image gathers for both primary (P) and converted (C) waves.
