[OpendTect_Users] Interpreting reflector with a phase shift

[Arnaud Huck]

Dear Michel,

Yes you will still be able to apply any stored volume or attribute on 
the interpreted surface. I forgot to mention that looking at the 
instantaneous energy (attribute) is a key to the localization of the 
interfaces to be mapped, regardless of the polarity of the data.

Regards,
Arnaud Huck.
