Files *.dat: Sample input data for the complete ray tracing program By Vlastislav Cerveny, Ludek Klimes, Ivan Psencik Date: 1996, September 30 The sample 3-D model consists of two layers and of the lenticular inclusion with edges, situated in the upper layer, see the schematic Figure 5 in V.Cerveny, L.Klimes, I.Psencik: Complete Seismic-Ray Tracing in 3-D Structures (In: D.Doornbos, ed.: Seismological Algorithms, Academic Press 1988). The files *.dat listed below contain the sample input data for the complete ray tracing program. The input data consist of the 7 data sets (1) to (7) listed in file 'crt.doc' (corresponding to lines (2) to (8) of input data for 'crtin.for'). Note that several data sets may be located in a single file. crt.dat... File containing the sample data set: (1) CRT model.dat... File containing the sample data set: (2) MODEL dcrt.dat... File containing the sample data set: (3) DCRT init.dat... File containing the sample data set: (4) INIT src.dat... File containing the source coordinates. Referred from INIT. code.dat... File containing the sample data set: (5) CODE rpar.dat... File containing the sample data set: (6) RPAR writ-s.dat... File containing the sample data set: (7) WRIT These demo data correspond to a very simple initial-value ray tracing of rays shot in a single vertical plane from the point source. For the two-point ray tracing in this model refer to data located in subdirectory 'len'. Remarks within the input data files: The comments in brackets situated at the ends of lines, after the input items, are not the part of the input data. They are just remarks placed so as to be skipped when reading the input data. The last input line of a data file is usually followed by (a) Empty line, line '====' and empty line, or by (b) Empty line, line '----', empty line, text describing the input data, empty line, line '====' and empty line. ========================================================================
