Domain might refer to any of several data dimensions, even within geophysics.
- Seismic interpretation: Travel time vs depth
- Seismic processing, spatial analysis: time–offset, Tau-p, f-k, Radon, etc.
- Time series analysis: Time vs frequency vs quefrency
- (Rarely) in pre-stack data: dimension in which traces are gathered, e.g. common offset vs common angle vs common receiver, etc.
