The inline bin size is chosen from the sampling requirement to avoid aliasing
of the steepest dip of interest. This requirement is represented by the equation

where is the minimum velocity of interest, the
maximum frequency expected in the data and the maximum
inline dip. With the
values in Table 2, I got which I will round to a
standard value of 20 m. With this, the inline bin size is 10 m. I could use
a similar computation to find the minimum cross-line sampling, but I will
simply assume that the bin is square since the model is complex enough to
have significant dips in directions other than the inline direction
(Figures and ).
The bin size is thus 10x10 m and the source and receiver intervals are
therefore both equal to 20 m.
