Attribute Description: The Hilbert trace is the trace generated by running the Hilbert transform on the original, or complex, trace which generates real and imaginary portions of the original trace. The imaginary portion is often called the Hilbert trace and is a 90-degree rotation of the real trace.
Interpretation Use: Since this attribute is a 90-degree rotation of the real trace, it can be used in the same way as the real trace is used. The big difference is that the Peak no longer represents the correlation of a zero-phase wavelet to the reflection coefficient series. This is often used to represent the interval layers more than boundaries.
This attribute will have the same spectrum as the real trace, so the same colorbars used for the amplitude traces can be used for the Hilbert attribute traces.
This is the imaginary g(t) portion of the complex, or analytical, trace which is defined as the real part of the trace f(t) and the imaginary part of the complex trace g(t):
This will be a 90-degree rotation of the real portion of the complex trace.
