Kinematic Analysis of Solar-Neighborhood Stars Based on RAVE4 Data
  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.
