Mobil data set contains missing near-offset traces as well as
a few randomly located missing traces, as shown in Figures ![[*]](http://sepwww.stanford.edu/latex2html/cross_ref_motif.gif)
and .
Those missing traces are interpolated by means of
the iteratively-reweighted least-squares method
that is explained in chapter 3.
For each CMP gather, twenty iterations are performed
in the conjugate-gradient algorithm.
The result of interpolation is shown in Figure .
It shows that both near-offset and randomly located missing traces
were successfully interpolated and the interpolated
traces follow the hyperbolic trend correctly in CMP gathers.
