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.
