Rotation velocity, V_rot, and velocity dispersion, σ, for the bulge of M31, as a function of galactocentric distance R. Negative and positive values of R correspond to opposite sides of the LUCI slit. The black dashed line in the upper panel marks the value of zero. The black solid curves show the kinematics from the optical (Paper I), while the blue and red curves plot the kinematics obtained with EMILES (Teramo) models in H- and K-band, respectively. Error bars correspond to 1-sigma uncertainties.
