    When  this button is clicked the following window will be displayed:

   The left  panel allows you to choose one of three following items corresponding to the three types of inversion considered in the Appendix.

(a) Amplitude spectra inversion
    After you have chosen this item, type in the upper right text box the value defining the numeric difference between the maximum and minimum residual. Only these possible orientations of the double couple principal stress axes which give the residuals between observations and synthetics within this interval will be shown in maps of the quality of different possible axes orientations.
   Click OK  , and the following results will appear in the  windows:
- Map of the quality of different possible T and P axes orientation. Every point in the map represents the stereographic projection of the axis orientation on the lower hemisphere. The color shows the quality of this orientation. In the case under consideration the maps forT and P axes are similar because of the symmetry considered in Appendix. That is why only one map is presented.
- Four equivalent best focal mechanisms and seismic moment.
- Residuals as a function of source depth (see Appendix).
- Observed and synthetic surface wave amplitude spectra calculated for the best values of variable parameters.
(b) Amplitude spectra + P polarity inversion
   After you have chosen this item, type in the upper right text box the difference between the maximum and minimum residual which you would like to be shown in the maps. Type in the lower right text box the number of best solutions to be shown in the  stereographic projections of nodal planes.  Click OK , and the following results will appear in the  windows:
- Maps of the quality of different possible T and P axes orientations.
- The best focal mechanism, selected polarities and seismic moment.
- A set of first N (N is the number typed in the lower right text box) best focal mechanisms and seismic moments.
- Residuals as a function of source depth.
- Observed and synthetic surface wave amplitude spectra calculated for the best values of the variable parameters.
(c) Amplitude  + phase spectra inversion
   After you have chosen this item, follow the instructions given in the previous paragraph (b).
