J/PASP/117/1          Radial velocities of 166 LHS stars         (Dawson+, 2005)

High proper motion stars. IV. Radial velocities of 166 Luyten Half-Second stars. Dawson P.C., De Robertis M.M. <Publ. Astron. Soc. Pac., 117, 1-12 (2005)> =2005PASP..117....1D
ADC_Keywords: Stars, late-type ; Radial velocities ; Space velocities ; Proper motions Abstract: We present 178 radial velocity measurements for 166 late-type stars selected from the Luyten Half-Second (LHS) proper motion catalog (Cat. I/87). Space velocities are given for all but two of them. Most of the stars lie within 25pc of the Sun, but the list includes a handful of high-velocity transients from the halo population. Description: The data were acquired as part of an ongoing service observing program using the 1.85m f/5 Plaskett Telescope at the Dominion Astrophysical Observatory from 1999 October through 2000 September.
