  The distribution of moving groups in the solar neighborhood has been used to
constrain dynamical properties of the Milky Way for decades. The kinematic
bimodality between the main mode (Hyades, Pleiades, Coma Berenices, and Sirius)
and Hercules can be explained by two different bar models -- via the outer
Lindblad resonance of a bar with a high pattern speed ($\sim$55 km s$^{-1}$
kpc$^{-1}$), or via the corotation resonance of a bar with a low pattern speed
($\sim$40 km s$^{-1}$ kpc$^{-1}$). Recent works directly studying the
kinematics of bar stars and gas flows near the center of the Galaxy have
converged on the low pattern speed model. In this paper, we independently
confirm this result by using Gaia DR3 to directly study the variation of
Hercules across Galactic azimuth. We find that Hercules increases in $V_\phi$
and becomes stronger as we move towards the minor axis of the bar, and
decreases in $V_\phi$ and becomes weaker as we move towards the major axis of
the bar. This is in direct agreement with theoretical predictions of a low
pattern speed bar model in which Hercules is formed by the corotation resonance
with stars orbiting the bar's L4/L5 Lagrange points.
