Rotation curve of the Galaxy seen by our Mira sample. Left: Galactocentric Transversal velocity Right: velocity dispersion of the Mira sample. We add the corresponding curves from Sanders et al. (2019) (black) and Du et al. (2020) (blue). We include the rotation curve derived from RC stars from Huang et al. (2020) (purple). The velocity and position of the Sun are showcased in yellow. The red cross and the dashed line indicate the position of the Galactic center at a value of $V_{\ell }^{\ast }=0$.
