Abstract:
Radial velocities for 114 Hipparcos stars, mostly high transverse
velocity binaries without previous radial velocity measurement, are
published. Measurements are made with the CORAVEL-type radial velocity
spectrometer. The accuracy of measurements is better than 1km/s. Two
stars, BD+30 2129A and HD 117466AB are found to be radial velocity
variables, and three more stars, HD 119515A, HD 131597AB, and
HD 153344, are possible radial velocity variables.

Note (1): Information on the notes:
CCDM = Double star identification from Dommanget & Nys 1994, Cat. I/274
GSC = Star number from GSC Catalogue (Jenkner et al., 1990, Cat. I/220).
Type of visual double stars detected by HIPPARCOS are marked:
HIP-C = HIPPARCOS double star component solution.
HIP-G = HIPPARCOS acceleration solution.
HIP-X = HIPPARCOS stochastic solution.
HIP-S = HIPPARCOS suspected double.
PA = Visual double star position angle in degrees.
d = Components separation in arcsec
Component magnitude difference:
ΔHp = HIPPARCOS broad-band Hp, ΔV = JohnsonV,
ΔRpg = photographicR, Δm = unknown system.
