(c) Data-smoothing statics methods assume that patterns of irregularity which events have in common result from near-surface variations and hence static-correction trace shifts should minimize such irregularities. Most automatic statics-determination programs employ statistical methods to achieve the minimization. Data-smoothing methods are generally applied to remove small residual errors after first applying methods (a) or (b). Second-order statics corrections are often called trim statics.
