Ray Abma contributed several drawn figures which illustrate the underlying filter technique. David Lumley made his migrated image of the salt anticline data available. Mihai Popovici obtained the image of the Texan fluvial reservoir and the corresponding coherency cube from CTC.
Sudhakar Vasudhaven of CTC made the Texan fluvial reservoir images available. Wook Lee of Unocal provided the salt dome data to SEP. Haliburton Geophysical Services released the salt anticline data to SEP. Without their help, this work would have been a tedious theoretical paper with an incorrect conclusion.
