Detailed Description

Implementation class: I/O from a CBVS pre-stack seismic data store.

Every (in)line is a CBVS cube. A gather corresponds to one crossline/trace number). Because CBSV seismics is inline-sorted, the crossline number is stored as inline in the cube. Upon retrieval actual BinID and Coord are restored.

In 2D, things are a bit more 'normal'. Every trace number is an inline and the crosslines are simply sequence numbers for the vaious offsets.

You can make an instance of this class, to construct file names.
