Description

2D ZO-MF search engine

 

This procedure execute the calculation of 2D zero offset MultiFocusing (ZO MF). The calculation can be performed standalone using CPU /GPU or remotely on cluster using CPU/GPU nodes.

Input data – seismic data and parametrization tables

Output data – Database file with calculated optimal MF parameters and corresponding to them time-corrected events

Input data

Storage file

GMFPickingItem

 Link to velocity constrain picking that can be taken from another procedure

File with picking

 File consists the velocity corridor. The search of the optimal MF parameters will be performed only        inside this constrain. If not specified the search will be performed for all velocities

SEG-Y data handle

Input sorted headers (of seismic data)

Input Stack Line

 Service object provides location of imaging point (output geometry)

MF Tables Parametrization

 Service object provides parameters for MF search
