Hello All

I am trying to move step by step on Zero Offset VSP Processing. Now, I am trying to apply band pass filtering to my data using this:

sufilter < xcor_output_20_sources_B1.su  f=5,10,15,20 amps=0,1,1,0 | filter_data.su

However, I did not understand how I should define the frequencies. I tried to leave the first two frequencies constant and changed the next two frequencies little by little. Then, I tried to subtract each other, using this:

sudiff file1.su file2.su > diff.su

Is there any effective way to choose these 4 frequencies in bandpass filtering? 

How should I learn my frequencies?

If you would like to check, I added my file here.

Thanks

Best Regards

Erdi
