V/94         Catalog and Atlas of Cataclysmic Variables  (Downes+ 1997)

A Catalog and Atlas of Cataclysmic Variables - Second Edition Downes R.A., Webbink, R.F., Shara M.M. <Publ. Astron. Soc. Pac. 109, 345 (1997)> =1997PASP..109..345D
ADC_Keywords: Atlases ; Stars, variable ; Binaries, cataclysmic Description: This catalog contains data for 1020 cataclysmic variables (CVs). It includes coordinates measured in the reference frame of the Hubble Space Telescope Guide Star Survey for non-novae and from the literature for novae. Also given are the variability type, the magnitude range, references to finding charts and spectroscopy, the galactic latitude and longitude, and the year of outburst for novae. The second edition includes plate identification information for the coordinate measurements, a reference to the classification, proper motion information where appropriate and a table showing the CVs observed by space-based observatories. This version of the catalog includes 195 new objects (172 CVs and 23 non-CVs), revised identifications for 57 objects, and revised classifications and spectral references where available. Introduction: A Catalog and Atlas of Cataclysmic Variables - Second Edition as presented here contains a list of all cataclysmic variables discovered prior to May 1996, as derived from the literature; there are a total of 865 cataclysmic variables (276 novae, 372 dwarf novae, 162 novalike variables, 47 objects classified only as cataclysmic variables, 6 interacting binary white dwarf (IBWD), and 2 possible supernovae/novae) and 155 object formerly classified as cataclysmic variables. A Catalog and Atlas of Cataclysmic Variables - Second Edition as distributed here is in two files. The first file contains the cataclysmic variables in constellation order, while the second contains the objects in order of increasing right ascension. The tables below give the characteristics of these files. A copy of the document catvar.tex should be transmitted with any additional copy of this catalog. File Summary:

Note on GCVS: The name of the object in the General Catalogue of Variable Stars (Cat. II/139B) and subsequent Namelists (Cat. II/195) (67th, Kholopov et al. 1985; 68th, Kholopov et al. 1987; 69th, Kholopov et al. 1989; 70th, Kazarovets and Samus 1990; 71st, Kazarovets, Samus, and Goranskij 1993; 72nd, Kazarovets and Samus 1995). For those objects without variable star designations (189), we list the constellation name only (which were derived from Roman (1987, Cat. VI/42). Since some constellations contain more than one object without a GCVS designation, we include a number after the constellation name. The non-GCVS designations are strictly provisional. Note on RAh, DEd: COORDINATES: For non-novae, the J2000 coordinates of the objects as measured in the Space Telescope Guide Star reference frame. The right ascension is given to the nearest 0.01s, while the declination is given to the nearest 000: 1; for objects that are very faint or not visible, the coordinates are given to a lesser accuracy. The accuracy of the Guide Star Catalog is 000: 4 in the north, and 000: 6 in the south (Taff et al. 1990ApJ...353L..45T). For the novae, the coordinates are taken from Duerbeck (1987SSRv...45....1D) or from the literature (for recent novae), and are precessed to the J2000 equinox. For those objects without available/usable finding charts (62 objects), coordinates have been obtained from the literature, and are generally given to a lesser accuracy than those objects measured in this work. The position of V890 Aql, which did not exist in the original table, has been added at CDS from SIMBAD database. Note on DEs: When the seconds of declination were not known, this field has been left blank. Note on VarType: CLASSIFICATION: The type of variability of the object. Table 3 lists the various types used in this work, which is based on the classification scheme used in the GCVS. Those types in upper-case letters are taken directly from the GCVS, while those in lower-case letters have been obtained from the literature (which was generally in agreement with the GCVS, and is presumably more secure); whenever possible, a type from the literature was used. There are 155 objects in the catalogue designated NON-CV, which are stars that have been previously catalogued as CVs, and are included for completeness; the references for these stars are those papers which refute the CV nature of the objects. The revised classification is given in the comment section below. Table 3: Variability Types Type Definition _ UG U Gem variable (dwarf nova) UGZ U Gem variable (Z Cam subtype) UGSS U Gem variable (SS Cyg subtype) UGSU U Gem variable (SU UMa subtype) UGWZ U Gem variable (WZ Sge subtype) N nova NA fast nova NB slow nova NC very slow nova NR recurrent nova NRA recurrent nova - giant donor (Webbink et al. 1987ApJ...314..653W) NRB recurrent nova - non-giant donor (Webbink et al. 1987ApJ...314..653W) SN possible supernova with no galaxy visible NL novalike variable UX novalike variable (UX UMa subtype) VY novalike variable (VY Scl subtype) (systems which undergo low states) AM AM Herculis variable (synchronous rotators) DQ DQ Herculis variable (non-synchronous rotators) CV cataclysmic variable (no type classification) IBWD interacting binary white dwarf M Mira variable I Irregular variable UV UV Ceti-type star Z AN symbiotic variable (Z And subtype) NON-CV not a cataclysmic variable (although once classified as such) NON-EX non-existent object PEC peculiar : uncertain :: very uncertain Note on max_mag, min_mag: MAG. RANGE: The MAXimum and MINimum magnitudes for the objects. For novae the primary source is Duerbeck (1987SSRv...45....1D), while for the non-novae the catalog of Ritter (1990, Cat. V/59) is the prime source. When no other references to brightness were available, the GCVS values were used. Note on sys_max, sys_min: MAG. SYSTEM: See Table 4.

Entries with a four-character code correspond to plate-IDs from the Hubble Space Telescope Guide Star survey; other codes refer to references in file coordref.dat. An asterisk (*) following the references means that there is a comment regarding the coordinate measurement, and those Downes and Shara (1993PASP..105..127D) references which have been superseded are listed as "deleted". Note on type_ref: CLASSIFICATION REF: A code for a reference to the CV classification. The file typeref.dat defines the codes from the literature. An asterisk (*) following the references means that there is a comment regarding the classification. Note on chart: CHART REF: for those objects with charts presented in the source referenced (168 objects) or in Downes and Shara (1993PASP..105..127D), a code for the original reference from which our chart is based. Note that the identifications of the CVs are based on the published charts (or in some cases coordinates only), and have not been independently verified by the authors. The file chartref.dat defines the codes and includes the numeric code used in the GCVS and subsequent Namelists. For novae (276 objects) a reference to the previously published chart in Duerbeck (1987SSRv...45....1D) is given (except for recent novae). An asterisk(*) following the references means that there is a comment regarding the identification, and those Downes and Shara (1993PASP..105..127D) references which have been superseded are listed as "deleted". The letter following some GVCS numbers in chartref.dat indicates the source of the identification as follows: a from Kholopov, Samus, Kazarovets, and Perova 1985IBVS.2681....1K b from Kholopov, Samus, Kazarovets, and Kireeva 1987IBVS.3058....1K c from Kholopov, Samus, Kazarovets, Frolov, and Kireeva 1989IBVS.3323....1K d from Kazarovets and Samus 1995IBVS.4140....1K Note on spect: SPEC REF: A code for a reference to a published spectrum; file spectref.dat defines the codes. A prefix of S indicates a spectrum in quiescence (394 objects), while a prefix of X indicates a spectrum in outburst (121 objects); we were unable to locate spectra for 350 objects. Whenever available, the quiescent spectrum was chosen for the catalog over an outburst spectrum. A colon (:) following the reference indicates that (i) the spectrum is only described, (ii) the spectrum is a glass plate tracing, or (iii) the reference is unconfirmed (only for a few novae in Duerbeck, 1987SSRv...45....1D), and those Downes and Shara (1993PASP..105..127D) references which have been superseded are listed as "deleted". Note on ID: OTHER NAME: A discovery or common alternative (non-GCVS) designation for the object.
