SEISMIC_DATA_SET (C028, C030, C049, C050, C053, C065, C115, C144)

(Rules) (Express)

Identifies the collection of seismic data that exists at a particular state of the processing. Processing that changes the data will normally create a new data set. The fundamental characteristic of data in this collection is that it is identified by some combination of source events, receivers and/or bin nodes and is not considered to be part of an earth model. Data which has direct references to earth positions must be stored elsewhere. The data set may represent the traditional amplitude as a function of time or it may represent data such as residual statics, velocity analysis (i.e., semblance as a function of time and velocity), filter scan (i.e., each amplitude trace representing a dominant frequency), velocity scan (i.e., each amplitude trace representing a constant velocity), velocity function (i.e., velocity as a function of time), F-K data (i.e., amplitude as a function of frequency and wave number), etc.
