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.
