Tau p domain
WebApr 21, 2024 · Tau-P domain muting is a powerful tool for removal of coherent linear noise such as refractions and direct arrivals, allowing for more open outer mutes. Alternatively, if using angle mutes or angle gathers, larger angles as primary energy (often obscured by direct arrivals and refraction energy) is uncovered and can be utilized. WebSix different versions (isoforms) of the tau protein are produced in the adult brain. The isoforms vary in length from 352 to 441 protein building blocks (amino acids). A region of the protein called the microtubule-binding domain, which is the part of the protein that attaches (binds) to microtubules, also varies among the isoforms.

WebIf Tau-P Transform was used to transform the data to the tau-p domain, then the tau value of the first sample of the tau-p trace is not zero and is in trace header entry TAUMIN. TDECON adds TAUMIN to the decon window start and end times. This means that Decon window start and Decon window end time should be picked on the original t-x
WebStrictly speaking, the method is applicable in the tau-p domain but has been applied to x-t gathers with certain assumptions. Here we extend this method to x-t domain by making the recursive process time dependent, thus accounting for the variation of the arrival angles as a function of time. WebApr 27, 1987 · ABSTRACT. In the x-t domain, the various raypaths collected in one trace have different ray directions, hence the travel times of primaries and secondaries are not …
WebJul 1, 1994 · The forward transform usually requires a p-direction deconvolution to improve the resolution in that direction. It aids the wave filtering by improving the separation of events in the tau -p domain. The p-direction deconvolution is required for both the linear and curvilinear tau -p transformations for aperture-limited data.
