Note 406(7): Final Version of Note 406(6)
In this final version it is shown that vacuum fluctuations are at a maximum for the propagation of light (Eq. (14)) and vanish in the Newtonian limit. So for light grazing the sun the vacuum fluctuations are maximized. In previous work it was shown that Eq. (15) produces a precessing ellipse. When vacuum fluctuations are added this equation becomes Eq. (17) which can be solved for <delta r dot delta r> in general.
