Velan.radon #145

Closed doziej84 closed 1 year ago

doziej84 commented 1 year ago

I am using the velan.radon script for velocity analysis....Pls what would make someone obtain a semblance panel like this? and what can I do to adjust it to be able to distinctly see the bulls eye and pick the stacking velocities? Has anyone encountered this while doing velocity analysis Screen Shot 2023-03-17 at 8 39 23 PM

Is your input data sorted in cdps? What is the fold of the data? It looks like you don’t have enough traces.

Your velocity spectrum is starting at 500m/s and goes to 2000 m/s. That seems to be a bit low.

Yes my data is sorted into cdp's. The maximum fold of the data is 47 and thats for only 2 cdp's. it goes as low as 1 for some Cdp's. the velocity spectrum above is for the cdp with 47. What range for velocity spectrum is good? I just attached a txt file showing the cdp's and fold available in the data fold.txt
