This processing technique automatically extracts reflection information continuously in space and time from the CDP input data. The reflection parameters are obtained by a systematic search in time and move-out which yield an estimate of arrival time T_i (X), amplitude A_i(X), and moveout ^DgrT_i(X) for each depth point. The combination of all the reflector segments for the line forms a reflector segment file consisting of all coherent events reflected from the subsurface including primaries, multiples, diffractions, and "false alarms."

Variations in band width and the picking aperture of both time and moveout are investigated in this paper. Land and marine field data are used to illustrate the results.
