Аннотация:A model of the Galaxy with the outer ring R1R2 can reproduce the observed distribution of the radial, VR, and azimuthal, VT, velocity components along the Galactocentric distance, R, derived from the Gaia EDR3 data. The best agreement between the model and observed velocities corresponds to the time 1.8 +\- 0.5 Gyr after the start of the simulation. The angular velocity of the bar of Omegab=55 +\-3 km s-1 kpc-1 and the position angle of the bar of thetab=45 +\-15 deg. provide the best agreement between the model and observed velocities.
