I am looking at figure 12.15, showing the conventional unit cell for the fcc lattice and in the plain view diagram on the right, the center point is labeled as a/2. Since there are points at the "top" and "bottom" face of the cube, shouldn't that point be labeled as 0 or 1 just like the points in the corners?
