ADC_Keywords: Stars, nearby ; Stars, M-type ; Spectroscopy ; Space velocities ; Stars, distances 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 Hα 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. File Summary:

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.

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, using a weighted combination of trigonometric and spectroscopic parallaxes.

Note (1): Components in a binary system are identified as p (primary) or s (secondary, tertiary).

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.
