Dear Peter,

in this directory are 30 files named saw12d.*km
that contain the saw12d model at different depths,
given in place of the star.
Each file has the following format:
depth longitude latitude anomaly(in % with respect to PREM).
Values are given every 2 degrees, as opposed to every degree
as I had announced before; I hope this is still OK.

The model was presented first in:

Li, X.-D., and B. Romanowicz, Global mantle shear velocity model
developed using nonlinear asymptotic coupling theory, J. Geophys Res., 101, 22245-22272, 1996.

I hope this help.

Merry Xmas,

Ludovic
