CIG from Kirchhoff Migration

Hi to everyone, I was trying to produce the CIG as an output of the Kirchhoff Migration. Using the program sfkirmigsr i saw that is possible to put cig=y instead of cig=n to produce them. But when I run this it gives me a "movie" of the section, what if I want to visualise only certain CIGs? I have to add a TARGET in the Flow or something else?

Thank you very much!
