Query: Rho-Omega Mixing and the Pion Form Factor in the Time-like Region   We determine the magnitude, phase, and $s$-dependence of $\rho$-$\omega$
``mixing'' in the pion form factor in the time-like region through fits to
$e^+e^- \ra \pi^+ \pi^-$ data. The associated systematic errors in these
quantities, arising from the functional form used to fit the $\rho$ resonance,
are small. The systematic errors in the $\rho$ mass and width, however, are
larger than previously estimated.
