Amplitude Frequency Spectrum #36

Open HHTC0 opened 6 months ago

HHTC0 commented 6 months ago

Hi @DaloroAT,

Hope that you are well. Hope you had good break from my requests :)

Is it possible to modify the spectrum functionality so that it give individual spectrum for each trace in loaded gather? Currently it gives average out spectrum for selected window.

Here is an example I could find https://www.researchgate.net/figure/Frequency-content-of-signal-Example-of-CRP-gather-of-14-position-in2-2-seismic-line-a_fig3_348750792

Regards

Hey @HHTC0

Could you describe it in more details?

I see the following options:

1) Select a window, calculate the amplitude spectra for each trace inside, and average them over the frequency axis (implemented right now). 2) Select a window, calculate the amplitude spectra for each trace inside, and plot spectra individually for each trace. 3) The same as 2, but by clicking on a specific trace. 4) Plot the full spectrum on the extra graph as a color image in (f-x) axes (it's your request, right? According to the attached image). 5) Something else?

Hi @DaloroAT,

Sorry for late reply. Though #1 is very useful to get the spectrum for any specific traces and would love to retain it. However yes, #4 is what I am after. It is generally the part of standard borehole seismic processing package. This would create spectrum for each trace that help analyze and display the loss of amplitude-frequency with depth, in the domain of VSP.
