SAC (Seismic Analysis Code), previously SAC2000, is a general-purpose interactive program designed for the study of sequential signals, especially time-series data. Emphasis has been placed on analysis tools used by research seismologists in the detailed study of seismic events.

Description

The SAC manual contains general information for the new user about what SAC can do, how it works, and how to get started. It also contains detailed information for the more experienced user on topics such as how to use SAC macros, how to read and write SAC data files from C or FORTRAN programs, and how the SAC program is structured.

You can get to the online manual through the following link:
