Green's function for 111 plane

Using the cubic basis I computed lattice and time averaged Green's functions for atoms separated along the x-cartesian axis. For the ordered and the disordered lattice the Green tensor components looked qualitatively similar to Fig. 1. In Fig 2 & Fig 3, I show the decay exponent of the Green's function with increasing separation.

NOTE:
(i)The averaging was done over 4000 independant frames and NOT 4000 tau as indicated below.
(ii) I also computed the VARIANCE of each Green's function tensor component (NOT PLOTTED).
