Conditions of Use
software is a beta test version of software we later plan to make fully
public, but at the moment we ask you to agree not to disseminate any
further copies of this version. If any of your colleagues would like to
use this software please have then contact with us directly.
want to remove any bugs, and correct problems in the documentation and
user interface before releasing the software. As a condition of using this
beta software we ask you to report all problems and to suggest
improvements that will make the software easier to use.

workers compute only the toroidal contribution
to the transverse component, and the spheroidal contribution to the radial
component. However, note that it is important not to omit the toroidal contribution to the radial displacement or
the spheroidal contribution to the transverse component, or errors on the
order of 1% can occur.

seismograms for transversely isotropic, spherically symmetric media.)

above two programs to SAC format.)
