  "abstract": "We consider stars with radial velocities, proper motions, and distance estimates from the RAVE4 catalogue. Based on a sample of more than 145000 stars at distances $r<0.5$~kpc, we have found the following kinematic parameters: (U,V,W)_\\odot=(9.12, 20.80, 7.66)\\pm(0.10, 0.10, 0.08) km s^{-1}, \\Omega_0=28.71\\pm0.63 km s^{-1} kpc^{-1}, and \\Omega'_0=-4.28\\pm0.11 km s^{-1} kpc^{-2}. This gives the linear rotation velocity V_0=230\\pm12 km s^{-1} (for the adopted R_0= 8.0\\pm0.4 kpc) and the Oort constants A=17.12\\pm0.45 km s^{-1} kpc^{-1} and B=-11.60\\pm0.77 km s^{-1} kpc^{-1}. The 2D velocity distributions in the UV, UW, and VW planes have been constructed using a local sample, r<0.25 kpc, consisting of \\sim 47000 stars. A difference of the UV velocity distribution from the previously known ones constructed from a smaller amount of data has been revealed. It lies in the fact that our distribution has an extremely enhanced branch near the Wolf 630 peak. A previously unknown peak at (U,V)=(-96,-10) km s^{-1} and a separate new feature in the Wolf 630 stream, with the coordinates of its center being (U,V)=(30,-40) km s^{-1}, have been detected.",
