Note (1): This is the number from the first column of the catalog from the 2nd edition (CGCCS, Cat. III/156). We have not introduced a new running number to avoid overcrowding of identifiers for an object. For new entries the running numbers begin with No. 6001 and are given in the sequence of R.A. (J2000). Note (2): In case of multiple finding lists, the coordinates are averages from multiple sources, heavily weighted in favour of the most accurate, if any. When Ste (for Stephenson) is included among the designations, the star has almost invariably been measured for position at the Warner and Swasey Obs. on one or even more objective-prism plates, with a resulting precision of 1-2". The astrometric reduction procedure used by Stephenson is explained in Publs. Warner and Swasey Obs. Vol. 2, No. 4, Sec. II. More than 2000 stars of the catalog have post CCCS position determinations done at the Warner and Swasey Observatory. The coordinates are given to 0.1 sec in RA and 1 arcsec in DEC, notwithstanding the precision class of the position of the object. The estimated precision of the coordinates is indicated in the last column. For many stars of CGCCS the equatorial coordinates have been improved on the basis of new determinations, e.g., by Aaronson et al. (1989ApJS...70..637A, 1990ApJS...73..841A), MacConnell (2000, Priv. Comm.), Maehara & Soyano (1988AnTok..22...59M, 1990PNAOJ...1..207M), Soyano & Maehara (1991PNAOJ...2..203M, 1993PNAOJ...3..259S, 1999PNAOJ...5..149S). For more than 300 carbon stars equatorial coordinates were taken from the Hipparcos Catalogue (I/239) after approximation to the format of this catalog. These stars can be recognized as bright stars with the highest precision class 0 in the last column of the catalog. Note (3): B magnitudes essentially all come from photographic plates; thousands of them are based only upon an average plate calibration used for an entire survey. Thus the magnitudes are almost never accurate to 0.1 mag, to which they are commonly given, and errors of over a whole magnitude should be common, even discounting variability. Note (4): V magnitudes essentially all come from photographic plates; For some stars V magnitudes from Paupers et al. (1993BaltA...2..268P) are used. Note (5): The infrared magnitudes are normally the sort defined by a Kodak N-type photographic plate exposed through a filter similar to the Schott RG8 or 695 filter. Such infrared magnitudes are close to the system of Kron & Smith (1951ApJ...113..324K), and have now been published for several thousand carbon stars. Note (6): This column displays the earliest more reliable determinations of spectral type in the R/N notation. Here also are classifications in the scheme of Morgan & Keenan (1941ApJ....94..501K); this scheme is still a good compact description of the spectrum. Sources of quoted classifications are coded here in parentheses. Below we list abbreviations for papers consisting mainly of reobservation of stars selected from finding lists: Bidun Bidelman, unpublished. De Dean (1976AJ.....81..364D). HD, HDE Henry Draper Catalogue and the extensions (Cat. III/135). The second extension, HA 112, is cited as CannMay49.. Her52 Herbig (1952, Trans. I.A.U., Vol. 8, 807). IRAS C Little-Marenin et al. (1987AJ.....93..663L) K-M Keenan & Morgan (1941ApJ....94..501K) Lund21 Lundmark (1921PASP...33..314). San41 Sanford (1941PASP...53..291S). San Sanford (1944ApJ....99..145S). Sh Shane (1928, Bull. Lick Obs., 13, 123). War Warner (1963MNRAS.126...61W). WPB Bidelman (1954ApJS....1..175B). Yam Yamashita (1972AnTok..13..169Y, 1975AnTok..15...47Y). Carbon star candidates in this column are marked by lower case c (Guglielmo et al., 1998A&A...334..609G and references therein). Note (7): This column gives the star's occurence in various finding lists, including unpublished ones. Some CCCS stars repeated here are still called unpublished, which means only that I had no reference to a separate publication when the CCCS went to press. For some of those stars, the CCCS is the only place they have been published; for others, they have since appeared in separate lists by their discoverers. In the latter case I have sometimes changed the discoverer designation to reflect separate subsequent publication, and sometimes not; in the great majority of cases, CCCS stars there called unpublished have since been confirmed in other surveys. There are finding lists with no special concentration on carbon stars. These are the Bright Star Catalog number, cited, as in all editions of the Bright Star Catalog, as an HR number (and usually put at the head of the list); HD or HDE numbers (listed as a number without other characters); BD or CD numbers in a notation close to the usual one; and the GCVS designation. The intent was to give CD numbers only if the CD magnitude is 9.5 or brighter. Any CPD (Cape Photographic Durchmusterung) nos. in the catalog are inadvertent unless spelled out as such, a fact due to the circumstance that carbon stars are red stars and the CD is red-biased, not only relative to the CPD but even, though this does not appear to be widely known, relative to the BD. Other finding lists: an explanation for the coding of these are in the "lists.dat" file. The largest unpublished lists are by Stephenson (Ste), a combination of stars now published in the CCCS and infrared survey products appearing in the present catalog; Sanduleak (Sndlk), whose entries are almost exclusively confined to CCCS stars; Victor Blanco (VB); and MacConnell (MacCon). Although there are several published MacConnell lists cited here, some of the MacCons may have since become separately published; but see also the special note under MacCon in the lists.dat file. Coding: Whenever a number appears separated from the initial part of the designation by a blank space, the number is a published one assigned by the corresponding discoverer, hyphens if any separating table numbers from numbers within tables. Numbers following alphabetic abbreviations without a blank space represent the year of publication where this was for some reason helpful to me (generally, where the same author has produced more than one paper). So "Kurt88 4" means star No. 4 in a table of carbon stars in Westerlund (1988, Astrofizika, 29, 405). The meaning of the abbreviations are in the "lists.dat" file. Here some comments on some abbreviations: D : The Dearborn Observatory objective-prism surveys for red stars. The carbon stars thus found were abstracted as lists of exclusively carbon stars, in the papers just cited, and were duplicated in longer lists containing all red stars found; the D numbers given in the catalog refer to the short lists, with one or two exceptions spelled out in the notes to the table. The notes also refer in other contexts to the "longer" Dearborn lists, with the meaning just explained. The "short" list numbers for carbon stars are continuous from paper to paper. Hen : Rybski (1972, unpublished). Most of the carbon stars discussed by Rybski were found on objective-prism plates by Henize, and by him assigned the numbers which Rybski refers to as Hen numbers and Stephenson quote in the catalog. There is no connection between these Hen numbers and others occurring in the literature -- even in the case of the occasional Hen numbers for carbon stars cited by Wray (1966, unpublished), who however, also assigns his own numbers and which are quoted in the catalog as Wray. Krum : L.E. Krumenaker, unpublished. At Warner and Swasey we had by 1972 taken duplicate objective-prism plates of the northern Milky Way for about half of the fields surveyed by Hamburg in the Hamburg-Cleveland survey for luminous stars in the Northern Milky Way. Although carbon stars were identified and measured for position by the Hamburg workers, and eventually published (Hardorp et al., 1973A&A....22..129H), the Hamburg limiting magnitude for carbon stars was not very faint (cf. Hardorp et al., 1973A&A....22..129H ). Hence Krumenaker searched for carbon stars on the new Case material already mentioned. On the other hand, the mag. limit for R/N classification is already fairly uniform between Hamburg and Cleveland (Stephenson, 1989PW&SO...3...53S). Kub : W.R. Kubinec, unpublished. These carbon stars are discussed by Kbinec, without position data, in 1989PW&SO...3...53S. He measured the approximate positions specially for the catalog. NassCol : The numerical C types quoted from this paper are defined in the paper; they essentially describe the CN strength, and the redness, of the spectrum in the infrared. Note (8): Four symbols were introduced in the CCCS and are retained here: (1) An asterisk indicates that the catalog equates two or more data in literal contradiction to one or more papers cited; for example, a much later paper may be reporting a new carbon star already so identified in a much earlier paper, which implies that perhaps there are two carbon stars in the area. This was a natural flag to use in the CCCS, where carbon stars were mainly reported in a few large and well-known surveys. It is no longer natural now, where the main pre-publication comparison has been with the CCCS, and there have meanwhile been many relatively short lists. Thus, I have added few if any new asterisks. Finally, a single asterisk meant that my fusing of two or more reports was based on coordinates alone, without any plate re-examination. In fact, many or most of these cases have now been routinely re-examined through later, systematic, surveys; but I have retained the asterisk to show the historical order. (2) A double asterisk means the same as a single one, except that I have specially re-examined plates with the identification problem in mind. As in (1), many of these have been further checked routinely by later, systematic surveys, where the finding of only one star allows the strong presumption that only one carbon star is involved. There are few or no new double asterisks in the present edition. (3) A plus sign signals a GCVS identification made by me by comparing an objective prism plate with a published identification chart. These, too, are mostly holdovers from the CCCS, because the host of more accurate coordinates for carbon stars in the present edition usually restricts any challenge to identifying a carbon star with a GCVS cool-giant variability type to the question (at least on deep plates): is there any other banded spectrum near the carbon star? (4) An R signals further remarks at the end of the catalog. The object of the remarks is twofold. First, remarks are intended as an extension to the entries Designations and Spectrum of the catalog comprising matter for which there was no place in the catalog. Second, remarks contain information about considerable disagreement in the position of a star determined by different authors or cases when there is some doubt if the data refer to the same star. We repeat Stephenson's remarks, although in a shortened form, in which he confirms discoveries or points to certain spectral and photometric peculiarities (outstanding spectral lines and bands, very red color etc.). Also we indicate the cases when a carbon star lies in the sky within boundaries of some star clusters and note conclusions about the membership, if possible. Also the stars with such distinguishing features as circumstellar silicate envelopes, detached gas and dust shells, maser emission, binarity and bipolar molecular outflows are marked. Note (9): Estimated precision class of the equatorial coordinates of the star: 0-1 for ±0.1 arcsec, 2 for ±1 arcsec, 3 for ±0.1 arcmin. Values of the precision class have been estimated by comparing coordinates of the stars determined by different authors. The highest precision class 0 was assigned only to the positions determined by Hipparcos, by MacConnell (2000, Priv. Comm) and for dwarf carbon stars.
