* Package name : seplib Version : 6.0 Upstream Author : Stanford Exploration Project * URL : http://sepwww.stanford.edu/software/seplib/ * License : Description : SEPlib is a complete and freely distributed seismic data processing software package. (Include the long description here.) SEPlib is a complete and freely distributed seismic data processing software package. SEPlib comprises several concepts and software pieces: * Data cube concept. The simple data base concept that underlies the original SEPlib package assumes the data to be regularly sampled in all dimensions. SEPlib stores such a "cube" as a matrix of numbers. It takes 2 files to store such a regular data cube: A data file stores the data values as one long array/ A separate header file stores house holding information such as the number of samples along each cube axis (eg. n1=1002,n2=256,n3=96) or the increment between samples (e.g. d1=0.004,d2=0.01,d3=0.025 ). * Data base concept for irregular data. Recently, SEP3d added support for irregular data to the basic data cube concept described in the last paragraph. * Seismic processing routines. SEPlib offers a collection of basic seismic processing routines such as Phase Shift migration (Phase) or a velocity stacking (Velan). These SEPlib programs perform simple operations. For complex manipulations several programs are stringed together via pipes. For example Spike n1=32 n2=16 k1=4 k2=4 nsp=1 | Phase inv=1 > data.H generates the modeling response of a diffractor in a constant velocity 2-D medium. Every routine prints its own documentation when it is executed without any argument. (When installing SEPlib you can convert these self documentations into regular UNIX Man pages). * Vplot, a graphics library. Vplot is a plotting package for UNIX systems. It supports line, area, text, and raster graphics primitives for many screen and hardcopy devices. Vplot is not restricted in any way to display seismic images, but it does it wonderfully. Especially its rastering and dithering of grey-scale plots and its sleek integration into the entire SEPlib framework make it a natural complement to the rest of SEPlib. * IO subroutine library. The core of SEPlib is its handling of input and output of data and header information. For example sreed() is a powerful, low-level subroutine that reads data from a SEPlib data file or the standard input. Equally important are subroutines such as putch or hetch and its companions that put parameters to the output history file or fetch them from the command line or the input history file. Standard UNIX man pages document these subroutines. * Preprocessors for FORTRAN code. FORTRAN 77 (and hence Ratfor) cannot allocate memory for arrays at runtime.
