[Wien] plane wave cut-off: the final word

Dear WIEN experts,
This question is trivial but I want to be sure I am on the right path.
I'm trying to reproduce a published WIEN2k calculation. In the paper,
the authors quoted the plane wave energy cut-off as 16 Ry.
In the user guide page 79, it states that Kmax*Kmax the plane
wave cut-off in Ry. But I've always known the cut-off to be
0.5*Kmax*Kmax. Which does WIEN use? In other words is
Kmax*Kmax = 16 or 0.5*Kmax*Kmax = 16 ?
Thanks!
J. Appleton
