I ran this and the only thing wrong I see (in the second plot) is some
white specks and other defects around z=0. The severity depends on the
viewing angle. They don't interfere with interpretation but I can see
how you wouldn't want those defects in a printed report. I saw
something like this in my own plots months ago but I can't recall what
I was doing.
