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.

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 1990ApJ...353L..45T). For the novae, the coordinates
are taken from Duerbeck (1987SSRv...45....1D 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.

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 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 r_RAh:
COORD REF: A code for a reference to the coordinates. 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 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 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 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 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 1985IBVS.2681....1K
b from Kholopov, Samus, Kazarovets, and Kireeva 1987IBVS.3058....1K 1987IBVS.3058....1K
c from Kholopov, Samus, Kazarovets, Frolov, and Kireeva 1989IBVS.3323....1K 1989IBVS.3323....1K
d from Kazarovets and Samus 1995IBVS.4140....1K 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 1987SSRv...45....1D), and those Downes and Shara
(1993PASP..105..127D 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.
