DOCUMENT EXAMPLE

In this section, we imitate a miniature SEP research paper. At SEP, such a research paper not only includes an article with figures, equations, and references, but also a set of accompanying programs, input data, and makefiles. In its electronic form such a research document enables the reader to reproduce the results that the document presents Schwab et al. (1996).

The research document that we embedded for documentation purposes implements Normal Moveout, a standard geophysical processing step. The equation that governs the Normal Moveout is a mapping from time t to zero offset time t₀

 

$$t^2 = t_0^2 + \frac{h^2}{V^2}$$ (1)

where h is the offset and V the subsurface velocity. We copied the underlying program and the following result from Jon Claerbout 1991.
