Inversion operators

The imaging operator I chose for this experiment is the downward continuation migration described by Prucha et al. (1999). This operator downward continues the wavefield, slant stacks at each depth step and then extracts an image at zero time. The regularization operator I used was a simple gradient operator along the offset ray parameter axis. This regularization operator assumes that the imaging is being done with the correct velocity model so that the events along the offset ray parameter should be flat. It will also reduce sudden variations in amplitude along the ray parameter axis.
