Hello Again

Can someone show me how I should assign the slope values (for example 4 values) in sudipfilt? If it is possible, showing on the screenshot, that would be great.

My data ( synthetic Zero offset VSP) parameters: my first geophone's position is 1000m depth, and the last geophone's position is 3000m depth. The Geophone interval is 20 m.

I added my data.

(Are there any visual sources for sudipfilt or any other things that I can utilize?

Thank you

Erdi
