Title: Comment on “Improved inversion for seismic structure using transformed, <i>S</i>‐wavevector receiver functions: Removing the effect of the free surface” by Anya Reading, Brian Kennett, and Malcolm Sambridge
Abstract: Reading et al. [2003] propose a transformation which takes the rectangular coordinate system ZRT to the ‘skew’ PSH system. The transformation isolates P ‐, SV ‐ and SH ‐waves of same slowness on the P‐, S‐ and H‐component, respectively, and removes the free surface effect. We have the following comments to their article: A) The transformation matrix in their paragraph has misprints propagated to the text in their Figure 1c. B) The LQT rotation [ Vinnik , 1977 ] has no leakage of P ‐displacement into the Q‐component, although a minor SV ‐leakage is present on the L‐component. C) The differences between PSH‐ and ZRT‐receiver functions are large, whereas the differences between PSH‐ and LQT‐receiver functions are very small in theory and hardly ever significant in practice.
