In the first step of the computation the system of rays creating ray tubes is traced running the program CRT with the main input data file 98-crt1.dat. For specification of ray parameters the data file 98-rpa1.dat is used.
The second step of the computation consists in interpolation within the ray tubes running the program MTT with input data 98-mtt.tmp created by history file 98-mtt.h.
The computation and the visualization of the results is managed by the history file 98-mtt.h. Download all the necessary files and type "perl go.pl 98-mtt.h" from the command line to run the computation.
The computed multivalued travel-time maps may be sorted according to the arrival time (i.e. first arrival to the gridpoints, second arrival to the gridpoints, ...) using the program MGRD. The sorted singlevalued travel-time maps may be then visualized using program GRDPS:
The computed multivalued travel-time maps may be also sorted according to the ray histories using program MTTGRD, and then visualized using program GRDPS:
