Tip radius Quantification and "Tip Image Size" on Deep indents

Hello,

I use AFM on very viscoelastic rubbery materials. This results in very deep indentations (100-200nm). My question is, is the tip radius check using the roughness sample acurrate to these indentations? I also realize that the parameter "tip image size" when altered can also change the value of the tip radius estimation that it gives you. What is the meaning of this parameter, and How do you optimize it?
