The mean values of their line-of-sight velocities have also been taken from various publications. As a result of our kinematic analysis, we have found the following parameters of the angular velocity of Galactic rotation: $\\Omega_0=29.34\\pm0.31$ km s$^{-1}$ kpc$^{-1}$, $\\Omega'_0=-4.012\\pm0.074$ km s$^{-1}$ kpc$^{-2}$, and $\\Omega''_0=0.779\\pm0.062$ km s$^{-1}$ kpc$^{-3}$.
