Sample data for 2-D model UNCONFORMITY (Cormier and Mellen 1984) Date: 2000, January 16 Written by Ludek Klimes Calculation of synthetic seismograms in 2-D model UNCONFORMITY: 'u2d-mod.dat'... 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-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). 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. Running demo data for program 'invtt.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 'invtt.for' program to yield the equations for the travel-time inversion. Data files 'u2d-mod.dat', 'u2d-src.dat', 'u2d-rec.dat', 'u2d-rpa.dat' and 'u2d-wri.dat' are common with the calculation of synthetic seismograms. 'u2d-pts.dat'... Additional input data file for the INVTT 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 INVTT program, containing the 'field' travel times from the source to the receivers. 'u2d-crt1.dat'... Data for two-point ray tracing of refracted P wave.
