Putting structural sensitivity and velocity uncertainty together, we
can define structural uncertainty simply as their product:
When converting seismic images from time to depth, it is also important to realize that the time-to-depth conversion itself is a mathematically ill-posed problem (Cameron et al., 2007) and has its own significant uncertainties.
