  Latitudes and Longitudes Ranges:
Enter Latitudes and Longitudes in either Degree (integer >= 0 only) & Decimal Minutes (can be in decimal between 0 & 59) or Decimal Degrees (between -90 & 90 for lat. and -180 & 180 for long. Negative values indicate South and West for lat. and long. respectively). These ranges will also be used for selecting seismic events.
 
 

Top/Max Lat: Deg. Min. Decimal Deg.

Bottom/Min Lat: Deg. Min. Decimal Deg.

Left/Min Long: Deg. Min. Decimal Deg.

Right/Max Long: Deg. Min. Decimal Deg.

Selection of Seismic (T-Phase) Event Data for Plotting:

OverPlot Seismic Events from Hydrophones and/or Seismic Stations
If OverPlot is set to No, no seismic events will be selected and only the bathymetric map will be generated. If it is Yes, seismic events within the Lat/Long limits defined above and other optional ranges defined below will be selected and overplotted using the defined color symbols onto the bathymetric map.

Year : Julian Day (1-366)
Hour (0-23) Minute (0-59) Seconde (0-59)

Select End Time:
Year : Julian Day (1-366)
Hour (0-23) Minute (0-59) Seconde (0-59)

Select Number of Hydrophones Used to Locate the T-Phase positions:
Between Minimum: and Maximum: hydrophones will be selected.
(Note that if Minmum Hydrophones Used = Maximum Hydrophones Used = 5 for example, only the data with 5 Hydrophones Used will be retrieved. Same situation applies to T-Phase Magnitude range.)

Select the Range of T-Phase Magnitude:
Between Minimum: and Maximum: T-Phase Magnitude will be selected.
