Written by Ludek Klimes
Calculation of synthetic seismograms in 2-D model UNCONFORMITY:
'u2d-ss.h'... History file to calculate and plot the
synthetic seismograms. It drives programs 'crt.for',
'green.for', 'greenss.for', 'ss.for' and 'sp.for'.
In addition to the above data files, file 'source.dat'
with the seismic moment tensor is required.
'u2d-mod.dat'... 2-D model UNCONFORMITY.
'u2d-src.dat'... Coordinates of point source.
'u2d-rec.dat'... Receivers (situated at the right-hand side of the
model box).
'u2d-crt.dat'... Data for two-point ray tracing of 22 elementary
waves.
'u2d-rpa.dat'... Parameters for 2-D one-parametric shooting.
'u2d-wri.dat'... Names of output files with two-point rays and
all points of intersection of rays with the vertical
reference surface (right-hand side of the model box).
Running demo data for program 'inv1.for' in 2-D model UNCONFORMITY:
'u2d-inv.h'... History file running 'crt.for' to trace the
two-point rays of the refracted P wave and then processing
the results by the 'inv1.for' program to yield the
equations for the travel-time inversion.
Data files 'u2d-mod.dat', 'u2d-src.dat', 'u2d-rec.dat',
'u2d-crt.dat', 'u2d-rpa.dat' and 'u2d-wri.dat' are common
with the calculation of synthetic seismograms.
'u2d-crt1.dat'... Data for two-point ray tracing of refracted
P wave.
'u2d-inv1.dat'... Sample main input data for the INV1 program.
This data file refers, among others, sample data file
'u2d-mod.dat' of the model specification package, which
has therefore to be located in the current directory.
'u2d-pts.dat'... Additional input data file for the INV1 program,
containing the coordinates of 3 points: the source point
(file 'u2d-src.dat' for CRT), and receivers (file
'u2d-rec.dat' for CRT).
'u2d-ftt.dat'... Additional input data file for the INV1 program,
containing the 'field' travel times from the source to the
receivers.
Comparing ray-theory and FD synthetic seismograms:
'u2d-fd.h'... History file to calculate and plot the ray-theory
and FD synthetic seismograms.
'u2d-hil.dat'... Data to higlight some differences between
ray-theory and finite-difference seismograms.
