- n2
(subdirectory with all files)
- n2-mod.dat
-
Input data for the MODEL subroutine package to
specify the model used in the example described in
Subsection 6.2 of Klimes and Kvasnicka (1994).
- n2-net.h
-
SEP history file for network ray tracing in model N2,
describing the input data and program execution.
- n2-net.dat
-
Input data file for the 'net.for' program
of the package 'NET'. The data file refers two files
'n2-src.dat' and 'n2-rec.dat' of this package, and to
output file 'vel.out' of the 'grid.for'
program. The three referred files should be located in
the current directory. Program 'net.for' should generate
four output files 'rays.out', 'end.out', 'tt.out', and
'err.out', containing rays, the first-arrival travel times
at the receivers (endpoints), and the first-arrival travel
times and their estimated errors in the rectangular grid
of points.
The data correspond to the example described in Subsection
6.2 of Klimes and Kvasnicka (1994) with the exception of
the number of gridpoints and maximum forward-star size.
Whereas 100*100*50 gridpoints are used in the paper, only
50*50*25 gridpoints are considered within the demo data
in order to comply with the array dimensions of the basic
version of 'net.for'.
- n2-src.dat
-
Additional input data file for the 'net.for'
program with the coordinates of a source point.
- n2-rec.dat
-
Additional input data file for the 'net.for'
program with the coordinates of receiver points.
- n2-sec.dat
-
Main input data file for the 'sec.for' program
of the package MODEL to generate the velocity isolines
in Fig.6 of Klimes and Kvasnicka (1994). The data file
refers file 'n2-mod.dat' of this package. The referred
file should be located in the current directory.
