The standard deviation, ,
of the total energies for the calculations
among the various codes in each of the four approximations is given as a function of atomic number *Z*
in Fig. 1.

Fig. 1. Standard deviation of the total energies obtained by independent codes, as a function of atomic number

The deviations exhibited in Fig. 1. are seen to increase somewhat with

The actual differences between the results of the several codes
are shown in the next four figures:
