Abstract

A-028 DETERMINING THE OPTIMUM MIGRATION APERTURE FROM TRAVELTIMES C. VANELLE and D. GAJEWSKI Institute of Geophysics University of Hamburg Bundesstr. 55 20146 Hamburg Germany Summary True amplitude migration is a task of high computational costs. These can be significantly reduced if the involved summation is carried out only over traces which really contribute to the stack result i.e. a limited aperture instead of the whole aperture of the expriment. We introduce a method to determine an optimum migration aperture that needs only traveltime tables as input information. These are also used for the computation of the true amplitude weight functions.
