  Bose-Einstein correlations of identically charged pion pairs were measured by
the PHENIX experiment at mid-rapidity in Au+Au collisions at $\sqrt{s_{\rm
NN}}$ = 200 GeV. The Bertsch-Pratt radius parameters were determined as a
function of the transverse momentum of the pair and as a function of the
centrality of the collision. Using the \it{full} Coulomb correction, the ratio
$R_{\rm out}/R_{\rm side}$ is smaller than unity for $<k_{\rm T}>$ from 0.25 to
1.2 GeV/c and for all measured centralities. However, using recently developed
partial Coulomb correction methods, we find that $R_{\rm out}/R_{\rm side}$ is
0.8-1.1 for the measured $<k_{\rm T}>$ range, and approximately constant at
unity with the number of participants.
