Extended Data Fig. 10: Energy shift in the LB and UB peak positions.

In the left panel (which is the same as Fig. 3d), the distance spanned, about 5 nm, is too small to distinguish the energy shift in the two bands (dashed lines). In the right panel, the data is extended out to r = 6.8 nm, where an energy shift in both LB and UB can be seen. See Methods for details.
