History of Data Gift from BP Amoco (2000)
Proprietary Considerations
If you use this data be sure to thank BP Amoco and reference John and Carl's
abstract. I'd appreciate it if you could reference my 2.5D migration paper too
(in which this dataset is also used):
Efficient two and one-half dimensional true-amplitude migration
by Dellinger, Gray, Murphy, and Etgen (which hopefully should appear in
GEOPHYSICS in the May/June 2000 issue).
Sam Gray says of this model:
This model is kind of bad because it seems to break everything, F-X,
Kirchhoff, everything. I think Marmousi makes Carl's point much better
than this model does.
Joe's reply to the question whether we can distribute this dataset to
other people:
``Any of those 2D datasets you got from me you can do whatever you want
with. Just thank BP Amoco for making it available if you publish or present
something with it.''
(Figure is Sam's attempt at making a good image using
this data.)
