Comment on 'Numerical calculation of modes of oscillation of the Earth's core' by D. E. Smylie, X. Jiang, B. J. Brennan and K. Sato

In a recent paper, Smylie et al . (1992) have referred to the issue of transport terms in the boundary conditions when applying the subseismic equation (SSA) in core dynamics. Here we wish to set the record straight concerning the erroneous interpretation of, and confusing references to, our own work on the subject.
