The passage around this formula

Collect the pieces. Three charts, the Newtonian centroid $\mathbf R_N$ , the observer-dependent stress-energy centroid $X^\mu(u,\Sigma)$ , and the canonical Newton–Wigner operator $\mathbf X_{\mathrm{NW}}$ , form a genuine, well-behaved sub-atlas. Define, for any two of them evaluated on the same hypersurface $\Sigma$ ,
