AMBER: Sander klambda question

    I'm working on a thermodynamic integration project using Sander, and
I'm not quiet sure I understand conceptually why the klambda value
should be set to 4 when atoms are disappearing during the perturbation
process. Could someone please enlighten me? I understand
mathematically this value keeps the integral finite as lambda
approaches 1, but beyond that I'm at a loss.

Thank you,
