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.

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.

  * 01-Feb-2012: Version 'A' (from the author)
           with the following modifications:
    -- main.dat: 'Planets' and 'Methods' columns brought up to date.
    -- biblio.dat: added 'HD' column (by request);
       'GrpName' column had a few minor changes
    -- groups.dat : renamed column 'n' to 'N', and made new column 'n' for
       'separation parameter'

  * 15-Mar-2012: Version 'B' (from the author)
           with the following modifications:
    -- main.dat: Corrected e_plx values where r_HIP=1
    -- groups.dat: added 14 new columns: AltName, Stream, & Group width cols

  * 30-Apr-2012: Version 'C' (from the author)
           with the following modifications:
    -- main.dat: corrected 22 entries in column 'Lc' where SpType contains "VI"
    -- main.dat: columns "Npl" and "Mpl" brought up to date.

  * 28-Jan-2013: Version 'D' (from the author)
           with the following modifications:
    -- main.dat: revised/corrected 623 entries in columns 'RV' and/or 'e_RV'
                 where 'r_RV' in biblio.dat contains "577"
    -- main.dat: revised columns pertaining to Note(18) to reflect revised
                 estimate of LSR (U,V) from (14.0,14.5) to (14.1,14.6)
    -- main.dat: columns "Npl" and "Mpl" brought up to date.
    -- main.dat: corrected SpType for HIP 32067
    -- biblio.dat: revised r_SpType for HIP 32067
