Amplitude corrections for pegleg multiples  

It is tempting, but false, to believe that after scaling a pegleg by the reflection coefficient of the multiple generator, the event is directly comparable to a primary reflection. Primaries and their respective multiples traverse different raypaths between source and receiver, and thus exhibit different amplitude-versus-offset (AVO) behavior and suffer different anelastic attenuation and geometric spreading losses. In section I derive the time- and offset-dependent ``Snell Resampling'' operator to normalize peglegs to their primary with respect to AVO and attenuation. In section I present a differential geometric spreading correction for peglegs, and finally, in section I present an algorithm to estimate and apply the multiple generator's spatially-variant reflection coeffiecient.
