FORTRAN or BASIC source code of seven computer programs mentioned in the text can be downloaded from the author's FTP site (see below). These are stand-alone programs for calibrating and testing seismometers and for standardizing noise specifications; they do not form a package for general seismic processing such as SAC, SEISMIC UNIX, PITSA, or PREPROC (see below). Whereever appropriate, the FTP subdirectory of each program contains test data, auxiliary files, and a Read.me file with detailed instructions. No graphics are included but some programs generate data files in ASCII format from which the signals can be plotted. The programs are:
