Description:
The Extended Hipparcos Compilation (XHIP) cross-references the New
Hipparcos Reduction (HIP2, Cat. I/311) with relatable data from a
broad survey of presently available sources. The resulting collection
uniquely assigns 116,096 spectral classifications, 46,392 radial
velocities, and 19,097 iron abundances [Fe/H] to Hipparcos stars.
Stellar classifications from SIMBAD and indications of multiplicity
from either CCDM (Cat. I/274) or WDS (Cat. B/wds) are provided.
Parameters for solar encounters and Galactic orbits are calculated for
a subset of stars that can be made kinematically complete.
Memberships in open clusters and stellar associations are assigned.
We also provide stellar ages from The Geneva-Copenhagen survey of the
Solar neighbourhood III (Cat. V/130), identifications of exoplanet
host stars, and supplemental photometry from 2MASS (Cat. II/246) and
SIMBAD.
