some clear differences between adjacent traces. This may substantially reduce the final
frequency content of the stacked data. Some contractors offer full interpolation of traces
onto bin centres or full pre-stack migration procedures that can correctly handle the
real trace positioning rather than assuming traces are regularly sampled at bin centres,
both of which provide for a mathematically better solution. Owing to the cost this is
not routinely applied at present, but with the ever-reducing cost of computer power and
the desire for higher-frequency data for improved interpretation it is becoming more
common.
