SeismicUn*x Help (v. 38)

     

This is a help browser for the core part of the SeismicUn*x (SU) free software package developed and maintained by the Center for Wave Phenomena (CWP) at the Colorado School of Mines. The SU project is directed by John Stockwell (john@dix.mines.edu).

The SU programs are arranged below in broad catagories. Clicking on a program name pulls up the selfdoc for that item. Your web browser's Find capability is useful if you have a name fragment in mind (e.g. sort or nmo). While programs may logically apply to more than one catagory below, each program appears only once.

For the many programmers who develop new SU applications (and fix the old ones), I have added a listing of non-graphics library routines and the full SEGY header abbreviations (i.e., segy.h) used in SU. This should be considered a minimal subset of the numerical routines in SU. Many others are embedded as subroutines in main programs.

This help page is current through version 38 (2005) and thus should be considered a historical archive. However, since SU grows by accretion, almost all of the programs given here will be in the current SU release, although there may occasionally be additional parameters and functionality in later versions. Finally, there will certainly be new codes in the current release that are not found here. Enjoy.
