Reply to the comment on “A comparison of the dispersion relations for anisotropic elastodynamic finite-difference grids” (H. Bernth and C. Chapman, 2011, Geophysics, 76, no. 3, WA43–WA50) by E. H. Saenger, published in November-December 2011

We acknowledge Saenger’s (2011) comments and welcome the opportunity to clarify the potentially misleading points. Throughout Bernth and Chapman (2011), we used the Cartesian grid cell as illustrated in their Figure 1a. Saenger (2011) rightly points out that the elementary cell is an octahedron (his Figure 1). We used the Cartesian grid cell for simplicity, and so it decomposes directly into Virieux cells. Provided that every reference …
