[gmx-developers] ewald_geometry = 3dc

I am using Gromacs 4.5.5. My system has a slab geometry in the xy plane, so
I am using ewald_geometry = 3dc in order to obtain a pseudo 2-D summation.
If you have time, I have two questions about ewald_geometry = 3dc, which is
implemented in ewald_util.c (which is located in src/gmxlib):
(1) Does ewald_geometry = 3dc apply to PME electrostatics (coulombtype =
PME)? Or does ewald_geometry = 3dc only apply to (standard, classical)
Ewald electrostatics (coulombtype = Ewald)?
(2) Does anyone know what literature paper this implementation of 3dc is
based on? Is it based on "Ewald summation for systems with slab geometry",
Yeh, I.; Berkowitz, M. L. in J. Chem. Phys. 1999, 111, 3155-3162?
Thank you so very much for your time!
