Given a hypocenter location and a set of travel-time grids, Time2EQ calculates predicted travel-times.
Overview - Running the program-Input - Output - Processing and Display of results - [NonLinLoc Home]
The Time2EQ program calculates predicted travel-times between one or more synthetic events and one or more stations. Predicted take-off angles at the source are also calculated if an event mechanism is given and the corresponidng take-off angles grids are available.
The Time2EQ program takes a single argument
InputControlFile which specifies the complete path and filename for an Input Control File with certain required and optional statements specifying program parameters and input/output file names and locations. See the Time2EQ Statements section of the Input Control File for more details. Note that to run Time2EQ the Generic Statements section of the Input Control File must contain the
TRANS (Geographic Transformation) statements.
In addition, the Time2EQ program requires:
The names, locations and other information for these files is specified in the Time2EQ Statements section of the Input Control File.
The predicted travel-times are written to an observation file in NonLinLoc phase file format.
The predicted travel-time files can be used as input phase/observation files for location with the program NLLoc.
