V/123A        Catalog of Cataclysmic Variables     (Downes+ 2001-2006)

A catalog and atlas of cataclysmic variables: the living edition Downes R.A., Webbink R.F., Shara M.M., Ritter H., Kolb U., Duerbeck H.W. <Publ. Astron. Soc. Pac. 113, 764 (2001)> =2001PASP..113..764D
ADC_Keywords: Atlases ; Stars, variable ; Binaries, cataclysmic Abstract: The Catalog and Atlas of Cataclysmic Variables (Edition 1: Downes & Shara; Edition 2: Downes, Webbink, & Shara) has been a valuable source of information for the cataclysmic variable community. However, the goal of having a central location for all objects is slowly being lost as each new edition is generated. There can also be a long time delay between new information becoming available on an object and its publication in the catalog. To eliminate these concerns, as well as to make the catalog more accessible, we have created a Web site which will contain a "living" edition of the catalog. We have also added orbital period information, as well as finding charts for novae, to the catalog. This catalogue supersedes the previous versions of 1997 (Cat. V/94) and 1993 (Cat. V/79). This version is dated February 2006, and supersedes the 2001 version (Cat. V/110) File Summary:

Note (1): Variability type is coded as follows: 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 NLV = novalike variable (V Sge subtype; Steiner and Diaz, 1998PASP..110..276S) 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) CBSS = close binary supersoft X-ray source IBWD = interacting binary white dwarf M = Mira variable I = Irregular variable UV = UV Ceti-type star Z AND = 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 (2): Magnitude range: For novae, the primary sources are Duerbeck (1987SSRv...45....1D) Duerbeck (2001, private communication), while for the non-novae, the catalog of Ritter and Kolb (1998, Cat. V/99) is the prime source. When no other references to brightness were available, the GCVS values are used. The magnitude definitions are: U = Johnson U B = Johnson B V = Johnson V R = Johnson R I = Johnson I c = unfiltered CCD f = m(2200) g = Gunn g h = Hipparcos magnitude system i = Gunn i j = SRC j (unfiltered IIIa-J) p = photographic r = red s = Sloan g* u = m(1400) v = visual w = m(3000) x = m(F336W) Note (3): Reference to the coordinates code, RefCoo: Entries of consisting of the letter C followed by a four-character code correspond to plate-IDs from the HST Guide Star survey Note (5): Chart reference code: 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. Note (6): Spectrum reference code: A suffix of S indicates a spectrum in quiescence, while a suffix of X indicates a spectrum in outburst. 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's atlas)
