The VTI Explorer is similar in operation to the CREWES Zoeppritz Explorer and to the CREWES Reflectivity Explorer. Those web pages should be referred for notes on general use. The present utility differs in that it explores the behavior of the P-wave reflection coefficient in the presence of anisotropy. The present version can calculate both exact and linearized coefficients for VTI (vertical transverse isotropy) media. For comparison it can also calculate exact (Zoeppritz) and linearized (Aki-Richards) coefficients for the corresponding isotropic media.

- Linearized VTI coefficients: Ruger, 1997, "P-wave reflection coefficients for transversely isotropic models with vertical and horizontal axis of symmetry", Geophysics, 62, 713-722.
