but they emphasise different aspects and therefore can make features that are hard to see in the origianl original seismic clearly visible.
They can therefore be interpreted on and also used as input to the geobody process.

Represents the mean of the instantaneous power spectrum and its unit is Hz.
Is independent of phase and amplitude, and is useful in indicating reservoir rock properties such as hydrocarbon, fracture zone detection , and changes in thickness
Instantanous Bandwidth
Defined as the absolute value of the derivative of the Envelope divided by the Envelope: ωB=|dEnvelope/dt|/Envelope.
...
Represents the Root Mean Square of the instantaneous power spectrum and its unit is Hz.
Relationships between the Instantanenous Frequency (center frequency), Dominat Frequency (RMS frequency) and the Instantaneous Bandwidth (spectral bandwidth). From "Instantaneous spectral bandwidth and dominant frequency with applications to seismic reflection data" by Arthur E. Barnes.
