This document describes a preliminary version of a long period array processing package designed around the FKCOMB algorithm for use on the ILLIAC 4 computer. FKCOMB is a general-purpose array-processing program that uses frequency-wavenumber analysis to produce a bulletin which lists signal detections and various statistics for each detection. Two data editing and reformatting modules prepare the seismic data for FKCOMB and can be modified for use with other seismic algorithms. Preliminary reformatting of the seismic data is performed by DEM1. The data is edited and fast fourier transformed by DEM2. The input parameters required for operating these programs and their subroutines are described in this document.
