Glossary
SLOWNESS: The slowness is the inverse of apparent wave velocity = sin(i)/v with i = incident angle and v = true wave velocity.
SUPPRESSION OF TIME-DOMAIN ALIASING: The suppression of the time domain aliasing is achieved by using the complex frequency technique. The suppression factor should be a value between 0 and 1. If this factor is set to 0.1, for example, the aliasing phase at the reduced time begin is suppressed to 10 percent.
MODEL PARAMETER GRADIENT RESOLUTION: Layers with a constant gradient will be discretized with a number of homogeneous sublayers. The gradient resolutions are then used to determine the maximum allowed thickness of the sublayers. If the resolutions of Vp, Vs and Rho (density) require different thicknesses, the smallest is first chosen. If this is even smaller than 1 percent of the characteristic wavelength, then the latter is taken finally for the sublayer thickness. ''' # noqa
