Strong lateral variations in velocity

In order to extrapolate in areas with strong lateral velocity variations, care must be taken with the stability of the extrapolation algorithm. In this section, I analyze the stability of the helical factorization, making comparisons with conventional Crank-Nicolson extrapolation.
