The CWP/SU: Seismic Un ∗ x package

Abstract Seismic Un ∗ x provides programs for processing seismic data, including the following tasks: (1) tape reading/writing, (2) trace sorting, windowing, geometry setting, (3) data format conversion, (4) frequency, frequency-wavenumber, 2D wavenumber filtering, (5) Fourier, Hilbert, Gabor and Radon transforms, (6) tau-p filtering, (7) trace attributes, (8) wavespeed profile construction for modelling and migration, (9) seismic modelling, (10) NMO and velocity analysis, (11) several types of DMO, (12) a variety of pre-stack and post-stack migration algorithms, (13) wavelet transform-based data compression, (14) wiggle-trace, image and graph plotting and (15) trace picking.
