You can see In the main window of the program (Fig. 1) the title containing the name and version of the program along with the name of the region if it has been defined (see Program configuration). Below is the Menu (Fig. 1.) The number and names of fields in the menu depend on the modules added to the program. The place of functions in the menu may be random and differ, for example, between computers.
Fig. 1 Main program window
- tools controlling the appearance of the waveform traces order (by name by default) - they allow you to choose the method of sorting seismograms
. The sorting methods depend on the sorting modules. The presented example, defined by two sorting modules: according to the distance from the epicenter and the times of the selected phases, includes the following options: Clear sort method, Sort by epicenter distance - this sorting requires parameters with the location of the station and the location of the focus, Sort by first phase - this sorting requires picking the phases first. The first phase is taken into account when sorting, no matter what it is. Stations without marked phases are sorted at the end by name. - tools that controls the visibility of traces:
allows you to switch the view of the three components
switches to the view of only the vertical components - Z;
- tools to control the appearance of waveforms (more on this topic see Controlling the view of seismograms):
fits the seismogram to the window,
reduces timeline scaling by 20%,
increases timeline scaling by 20%,
moves the time window to the left,
moves the time window to the right,
reduces the magnification of records by 20%,
increases the magnification of records by 20%;
- seismic waves picking tools (more on this topic see chapter ):
allows you to select the appropriate phase for pointing,
icons of the most frequently used phases (up to five, their arrangement may change while working with the program),
allows you to remove phase suggestions;
- seismogram view settings support tools:
saving the view of the seismogram,
returning to the previous view of the seismogram.
redoing the undone view of the seismogram.
A seismogram is displayed below the toolbar. Methods of reading a seismogram and working with them are described in the Basic operations chapter. Fig.1 presents in the main window of the program an example of a seismogram recorded by the Son Tranh 2 seismic network in Vietnam, which was loaded using the Open waveform files option from Menu → File field or by pressing Ctrl+Alt+ O and selecting a file, e.g. VN.PHI_20130903000815.msd (see Reading seismic records from a file).
Stream names are written in the upper left corner of each trace in the form of network name, station name, location name, and channel name, separated by dots and, if the channel was filtered, information about the filters used in it is added. If the window area for a given route is very narrow, the ranges of vibration amplitudes are listed in brackets after the name of the route. If the seismogram area is wide enough, the amplitudes of signals are described on the Y-axis of a given route, and only physical units are given after the name. With a large number of channels, the route indicated by the mouse is enlarged. The selected stream (after clicking on it with the mouse) changes its color to blue. The start time of the seismogram is described in the upper right corner, and the X axis is a time axis showing hours, minutes, or seconds depending on the density of the seismogram. In the footer of the main program window, on the right, you can read the current position of the mouse cursor, i.e. route name, time, and amplitude.
You can in the main window, view seismograms, select phases, select streams for calculations, and call functions defined in modules. The main window is always displayed.
The appearance of the seismogram can be controlled by: the mouse wheel, mouse movements, and arrow keys in combination with function keys. The general rule of using the function keys is as follows: Shift to shift in time, Ctrl to compact and stretch in time, and Alt to enlarge and reduce one channel. More information can be found in the chapter Controlling the view of seismograms and Appendix A - Basic operations with the mouse and keyboard on a seismogram.
