After filtering the reconstructed wavefields with pseudo WDFs, we can
perform imaging with normal procedures. For the case of wavefields
parametrized as a function of data coordinates, we obtain the total
wavefield at image coordinates by summing over receiver coordinates
Similarly, for the case of wavefields parametrized as a function of
image coordinates, we obtain the image by application of the
conventional imaging condition extracting time from the pseudo
WDF of the reconstructed wavefield:
