AMBER: switching function for electrostatic interactions

Dear all,

I am a little confused about which type of cut-off is used by sander or pmemd
when computing electrostatic interactions with PME.
I first thought that it was a sharp cut-off as is the case for van der Waals
interactions, but in the manual, I read that a cubic spline switching
function is used. I have tried to find an answer in the mailing list and in
the FAQ but did not find it (or did not understand), so I apologize if this
question has already been answered some time ago.

Thanks in advance for your help,
