Replying to [comment:2 rhaas]:
I am not sure I understand what the difference between the parity
symmetry you describe and thorn reflectionsymmetry with reflect_x = reflect_y = reflect_z = yes is.
The system is not x-reflection, y-reflection, or z-reflection symmetric. Rather, the only symmetry is (x, y, z) -> (-x, -y, -z). I.e., this is a bitant symmetry where we use (x,y,-z) -> (-x, -y, +z) to fill in the z<0 ghostzones.
