Seismic Un*x provides programs for processing seismic data, including the f
ollowing tasks: (1) tape reading/writing, (2) trace sorting, windowing, geo
metry setting, (3) data format conversion, (4) frequency, frequency-wavenum
ber, 2D wavenumber filtering, (5) Fourier, Hilbert, Gabor and Radon transfo
rms, (6) tau-p filtering, (7) trace attributes, (8) wavespeed profile const
ruction for modelling and migration, (9) seismic modelling, (10) NMO and ve
locity analysis, (11) several types of DMO, (12) a variety of pre-stack and
post-stack migration algorithms, (13) wavelet transform-based data compres
sion, (14) wiggle-trace, image and graph plotting and (15) trace picking. (
