416 8. CDP SORT AND BINNING

FIG. 8.11 (A) First and (B) last 100 CDPs of a 2D seismic line. Every three CDPs are displayed for simplicity (bottom) with
the fold distribution graph (top). The number of traces in the CDPs slightly increases at the beginning from 1 to its optimum
value of 48, and vice versa for the end of the line.

flex binning works fine. Because the other goal checking the percent of offset bins filled by the
of flex binning is to provide a uniform offset dis- flex binning, as well as the range of the offset
tribution along the survey area, it is also worth values in the bins.
