1. Seed Waveform. The User selects a Seed file from the Episode database, or after applying the ‘Signal Download Tool’ (Figure 2, see “Data Handling Applications” chapter).
2. Catalog: The User selects a Seed file Seismic Catalog from the Episode database (See "AH Episodes" chapter)
3. Seismic Event. The User select selects a seismic event which has been downloaded after applying the ‘Signal Download Tool’ (Figure 2, see “Data Handling Applications” chapter).
4. Seismogram picks: P-wave first arrival phase picks, selected by the User from the waveforms (described below)
5. Ray Tracing Angles. Ray tracing angles table uploaded from the selected Episode database (see "AH Episodes" chapter).

...

NOTE: Although it is not necessary to pick P-wave arrivals in all of the waveforms to run the application, a minimum of 8 picks is required for the application to proceed to the calculations (stated also at the bottom of Figure 54). The number of the seismograms and P-wave phases picked, are updated, each time the User selects makes a new picking.

...

For most of the additional parameters required to execute the application a brief description is already given on the screen (Figure 65).

Event Coordinates [km]: The hypocentral coordinate of the event can be taken from the catalog ("get event from the catalog" tab, Figure 5), however the User has here the chance to modify the given values, or retry the process with different e.g. depths.

...

Select Output solution types: All options are described next to the boxes. The User may tick any of them he/she wishes, or select all of them by putting a tick in the box indicated by green color in Figure 6.5

Advanced Options: (NOT IMPLEMENTED YET)
