Scientific paper

File table1 contains the name of the observed stars, coordinates, astrometric data, radial velocities and notes. Parallaxes are taken from van Leeuwen (2007, Cat. I/311) and proper motions from (2000, Cat. I/259). Radial velocities were derived from high-resolution spectra taken with the FOCES spectrograph at the Calar Alto observatory (Almeria, Spain) and the SARG spectrograph at the Telescopio Nazionale Galileo in La Palma (Canary Islands, Spain). Additional spectra from the public library "S4N" (Allende Prieto et al., 2004, Cat. J/A+A/420/183) were also used. Radial velocities were measured by cross-correlating the spectra of our programme stars with spectra of radial velocity standard stars taken from Barnes et al. (1986PASP...98..223B), Beavers et al. (1979PASP...91..698B), and Udry et al. (1999ASPC..185..383U, 1999ASPC..185..367U). For known spectroscopic binaries the radial velocity of the centre of mass of the system is given. These values are from Pourbaix et al. (Cat. B/sb9/) or Eker et al. (2008, Cat. V/128 ). Previous radial velocities reported in the literature are also given for comparison.
