Note : this is the description file of the original catalog. This HTML page corresponds well to the original description, but some minor changes in the format may have been introduced in the FITS output files in order to allow for arithmetic operations on quantities such as coordinates and times. h:m:s and d:m:s units are normally converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the units; the value given in the HTML files supersedes the value indicated in the ReadMe file for this catalogue.

    Description:
        The Third Catalogue of Nearby Stars (Gliese & Jahreiss, "Preliminary
        Version of the third Catalogue of Nearby Stars" (CNS3), 1991, catalog
        V/70) includes over 1850 stars which lie north of Dec.= -30° and
        are either identified as spectral type M, or are unclassified but with
        an absolute visual magnitude estimate MV > +8.0. Although there is
        no uniformity in selection criteria, and many of the stars lack basic
        data (radial velocities, spectral types, accurate photometry), the
        observational properties of these stars underlie most estimates of the
        fundamental characteristics of the Galactic Disk. We have obtained
        optical spectroscopy of 1746 of the 1876 stars -- the remaining 130
        are binary companions of brighter stars and inaccessible to our
        observations. These spectra allow us, first, to exclude 61 stars as
        either degenerates or as misclassified earlier-type (B-K) stars lying
        beyond the 25 pc limit; to establish radial velocities accurate to
        ±10km/s for all stars confirmed as late-type dwarfs; to determine
        spectral types and absolute magnitudes from the TiO bandstrength,
        allowing more accurate distance estimates for stars with inaccurate
        (or no) trigonometric parallax measurements; and to identify stars
        with H{alpha} emission (chromospherically active stars) and with
        strong CaH absorption (perhaps including some metal-poor disk
        subdwarfs). We have determined the nearby-star luminosity function
        from complete samples derived by applying both the distance limits
        defined by Wielen (1974, Highlights of Astron. 3, 395) and by using
        limits derived from our own analysis. Spectroscopic data for the
        southern stars (Dec.<-30°) in the PMSU survey are also presented.
        The data were combined with the data from paper I to obtain a list of
        all the magnetically active dMe stars in the survey.

            (Nomemclature Note: should be named MCC         =Cat. III/13)
    Note (2): Flags as follows:
       a = Low quality trigonometric parallax
       b = Poor photometry
       c = Accurate parallax and good photometry. Both components of Gl 799
           lie above the main-sequence.
       e = 629 (Hy 207) appears twice in the preliminary version of the CNS3
       g = 2172: This star is not listed as double in the LHS
       h = 2426 (GJ 2112 A): Eggen (1980ApJS...43..457E) notes that this
           star appears to be a double in good seeing, but there are no
           confirming observations.
       i = 2805 (GSC036B-821) is listed in the CNS3 as a companion of V796,
           but the authors find that the radial velocity differs by 50km/s
       j = star from Brosch & Goldberg (1994MNRAS.268L..27B)
       k = star from Irwin et al. (1991MNRAS.252p..61I)
       * = star position corrected at CDS (see also the file "errata.htx")
    Note (3): Components in a binary system are identified as
          p (primary) or s (secondary, tertiary).
    Note (5): Flag as follows:
       a = CNS3 lists a photographic magnitude - the authors assumed an
           (m(pg)-V) colour of 1.5 magnitudes
       b = CNS3 lists a `photometric' magnitude for this star
    Note (6): Distance and estimated uncertainty (%) from the authors' data, using
         a weighted combination of trigonometric and spectroscopic parallaxes.
    Note (7): Flag as follows:
       c = Spectral type from Kirkpatrick et al (1995AJ....109..797K)
       d = Strong CaH - probable metal-poor disk dwarf or halo subdwarf
       f = 1752: Leggett & Hawkins (1988MNRAS.234.1065L) suggest, on the
           basis of JHK colours, that this star might be a giant, but our
           spectra are consistent with classification as a dwarf. Note that
           the V magnitude listed by LH88 is 8.07, while the CNS3 magnitude
           is 11.4 (photometric estimate). The authors observed a star of
           the latter magnitude. There is a nearby 8th magnitude SAO star
           (SAO 7382) - listed as K5, luminosity class unknown but µ~0"/yr
           which Leggett & Hawkins may have observed by mistake.
       k = Spectral type from Kirkpatrick et al. (1995AJ....109..797K)
    Note (8): Numbers 3804 to 3810 are the additional stars from
              table 1d in paper I.
    Note (9): Origin of distance and absolute magnitude as follows:
       C = distance and absolute magnitude from CNS3
       S = distance estimate is based on the authors' spectroscopic data
       p = Distance estimate is based on trigonometric parallax

    Note (1): Flag as follows:
       c = Gl 452B (1863) is listed as an f-type companion to Gl 452A, 7.5
           magnitudes fainter and ~15 arcseconds distant. We were unable to
           locate this star on the TV guider (rlim ~21) of the Keck telescope.
       d = The companion to LHS 2789 (2172) is listed in the LTT, but not in
           the LHS and may not exist
       e = Known VLM companion - Forrest et al., (1988ApJ...330L.119F)
       f = Eggen (1980ApJS...43..457E) noted that the primary star appeared
           double in good seeing, but there is no strong evidence for a
           binary companion.
    Note (2): Absolute magnitudes have been calculated using the magnitudes
         listed in the CNS3 and the distance estimate to the primary star
         (either from CNS3 or main file)
    Note (3):
       a = CNS3 lists a photographic magnitude
       b = CNS3 lists a 'photometric' magnitude estimate
    Note (4): Distance and estimated uncertainty (%) from the authors' data,

    Note (1): Flag as follows:
      a = Gl 127.1B probably does not exist. Gliese (1969, Veroff. Astr.
          Rechen-Instituts, Heidelberg, Nr. 22) lists a 'red companion at 8
          arcseconds', but no companion brighter than R~17 was visible with the
          LCO Du Pont telescope. Bessell (1990A&AS...83..357B) lists colours of
          (B-V)=0.615, (V-I)=0.70, suggesting either a white dwarf companion or
          observations of a background star.
      b = Our spectrum indicates that this star is an M-dwarf, but the
          6th magnitude primary, CP-73 2192, at 8 arcseconds distance prevents
          accurate bandstrength measurements.

    Global Notes:

    Note (G1): Source of positional data as follows:
       0 =  P60
       1 =  P200, Keck
       2 =  GSC
       3 =  CNS3
       4 =  Digital Sky Survey.
           Since completing the text of this paper, the authors used the
           on-line Digital Sky Survey to check all stars where the positions
           differ by more than 15 arcseconds from the CNS3 data.  They
           assumed mean epochs of 1954.0 and 1980.0 for POSS I and UKST
           plates in deriving positions from the DSS.
