[Ifeffit] Neagtive amplitude

[abhijeet gaur]

Hi all,
          I am fitting a *copper foil* . I am getting a good fit after using
the *4 single scattering paths* but in case of *fourth path* I am
getting *negative
amplitude*. What should be the *probable reason* for that as I am getting a
*very good fit*.

with thanks
