Talk:Amplitude versus offset

Intercept and Gradient
This article needs an explanation of the Intercept and Gradient concepts. It could also use a definition of the 4 basic classes of anomalous AVO responses. Hamsterlopithecus (talk) 14:34, 11 June 2010 (UTC)
 * I've reworked the introduction, added some background theory and I'm working on this now. Nwhit (talk) 15:11, 9 February 2012 (UTC)

Small errors in the Intro Diagram about the geometry
User:Nwhit has made an excellent diagram for the intro section of this article but it has 2 small errors. Other than that, it's all looking great! <--Offset_3-->  <--Offset_1--> -Hamsterlopithecus (talk) 00:52, 1 January 2014 (UTC)
 * The "offset" definition should probably be something like R_n-X_n. But I think it would be even more useful to just draw a double sided arrow showing the offset distance directly on the digram (above the common midpoint) and not on the legend. Something like this:
 * The angle shown on the diagram is not the angle of incidence, it is it's complementary angle. The angle of incidence if measured between the ray path the vertical.
