The diagnostic power of various displays of the Gabor transform has long been recognized, and such displays can be very intuitively instructive. Accordingly, we have extended the latest version of our surface-consistent, iterative Gabor deconvolution module, Gabor_sc, to include an alternative, diagnostic mode. In this mode, the program yields Gabor spectra, output as seismic traces, which can be displayed using Trace Display in ProMAX, or any other suitable seismic trace display operation. We demonstrate this new diagnostic mode here and show four examples where it has already proved its usefulness: studying parameter sensitivity; deconvolution operator design; deconvolution algorithm fine-tuning; and vibroseis sweep design.
