Description:
    This catalog was constructed at the Royal Greenwich Observatory in
    order to enlarge the Gliese (1957) compilation. It contains data on
    stars nearer than 25 pc that are not included in Gliese's catalog,
    plus additional information published since 1957 on stars in the
    Gliese catalog. The machine version contains essentially all
    information given in Table Ia of the published catalog, plus
    positional data, and most cross references to other catalogs given in
    Table IIa. The notes flags in Table Ia are not included because the
    notes are not machine-readable. Omitted from Table IIa are the
    finding-chart indicators (Lowell G numbers or notes references) and
    miscellaneous cross identifications to other names and catalog
    identifiers. Tables Ib and IIb, containing 21 systems originally
    included in Gliese's (1957) catalog but for which revised parallaxes
    have placed them farther than 25 pc are not included in the machine
    version.

    Data in the machine version are Gliese number (Newly added stars begin
    with 9001, but new parallaxes have removed 9419 and added 9849 and
    9850; the Sun [first record] has number 0); component identifications
    for multiple systems; parallax; annual proper motions; radial
    velocity; (U,V,W) space velocities; box orbit parameters (omega, e,
    i); spectral type; UBV data; absolute visual magnitude; right
    ascension (B1950) declination, GCTP (Jenkins 1952, 1963); HD DM, GCRV
    (Wilson 1953) and other catalog identifiers; BS (= HR) (Hoffleit 1964)
    numbers; and remarks codes for SB, doubles, variables, etc.

    Please note that the first entry is for the Sun, and thus it lacks
    fields such as RA and Dec.

Note on Woolley:
    Star sequence numbers less than 1000 are from Gliese (1957);
    new stars have a number > 9000; The Sun is #0 (and therefore lacks entries
    in fields such as the RA and Dec.

Note on e_plx:
   "S" indicates spectroscopic parallax

Note on n_RVel:
    J = combined components of binary
    V = variable velocity

Note on GCdist:
    i.e GCdist represents parsecs if the Sun distance is 10kpc. See
    also in file "adc.doc"

Note on LC_Code:
    1 = I or c;   2 = II or c;
    3 = III or g; 4 = IV or sg;
    5 = V or d;   6 = VI or sd;
    7 = D or wd.
    Intermediate classes have no codes, e.g. 4 is given for IV-V.

Note on r_SpType:
    1 if MK;
    2 if combined MK type for multiple system;
    4 if combined non-MK;
    blank  if non-MK.

Note on n_Mag:
    J = combined light for multiple system
    P = Mag indicates a photographic magnitude
    V = variable magnitude

Note on Mv:
    Visual magnitude is reported to 0.01 mag if both probable error of
    parallax < 10% and V is given to 0.01 mag.

Note (1): see details in file "adc.doc" or in the original publication.

Note (2): the codes are
   2 = spectroscopic binary
   3 = spectroscopic triple
   4 = unresolved double, unknown nature
   5 = UV Ceti flare star
   6 = eclipsing binary
   7 = semi-regular variable
   8 = astrometric binary
   9 = planetary nebula

Historical Notes:
  * 19-Jul-1994: The file has been reformatted at CDS from the CD-ROM
    version "Selected Astronomical Catalogues Vol.1" with addition of
    decimal points when required (blank numbers in the decimal part) and
    conversion of RVel and Mag codes.
  * The 1950 declination of Gliese 157B (record #350) was corrected.

  * 21-Jul-1997: This document was brought up to current CDS/ADC standards.
