V/137D        Extended Hipparcos Compilation (XHIP)          (Anderson+, 2012)

XHIP: An Extended Hipparcos Compilation Anderson E., Francis C. <Astron. Letters 38 (2012)> =2012AstL...38..331A (http://arxiv.org/abs/1108.4971) =2012PAZh...38..374A =2012yCat.5137....0A
ADC_Keywords: Stars, bright ; Combined data ; Cross identifications ; Positional data ; Parallaxes, trigonometric ; Proper motions ; Stars, distances ; Spectral types ; Radial velocities ; Abundances, [Fe/H] ; Stars, ages ; Space velocities ; Milky Way; Clusters, open; Associations, stellar; Photometry, UBVRI ; Photometry, infrared Keywords: astrometry; spectrography ; radial velocities ; spectral classifications ; iron abundances ; photometry ; solar neighbourhood ; kinematics ; open clusters; stellar associations; exoplanets ; photometry 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. File Summary:

Note (27): the separation parameter n is a measure of the concentration of a cluster, and of its separation from the surrounding star field (low values show poor dynamical separation from surrounding stars). A value of 5 is usual for a cluster, while 3.5 is typical for an association. Note (28): see 2012MNRAS.422.1283F (arXiv:1202.1375)
