\begin{abstract}

The {\em General~Catalogue~of~Variable~Stars} contains information necessary for
obtaining observations of variable stars and, in particular, cataclysmic
variables. However, the coordinates presented are not accurate enough for
observatories such as the Hubble Space Telescope, and the references to finding
charts are often to journals not easily accessible to some astronomers. We have
therefore created a catalog of all cataclysmic variables (known to us as of 1992
February), which contains coordinates (measured in the reference frame of the
Hubble Space Telescope Guide Star Survey for the non-novae and obtained from the
literature for the novae), the variability type, the magnitude range, and
references to both finding charts and spectroscopy. The atlas contains finding
charts for the dwarf novae, nova-like variables, and objects classified only as
cataclysmic variables, for which we could obtain valid identifications; a
similar catalog and atlas for novae has been published by Duerbeck (1987a).

\end{abstract}

\section{Introduction}

{\em \cat} as presented here contains a list of all cataclysmic variables
discovered prior to February 1992, as derived from the literature. The catalog
has the same basic format as the {\em General Catalogue of Variable Stars} with
the following enhancements:

\blankii
1)~More accurate coordinates for the CVs, derived from the {\em Guide~Star
Catalog}~(Lasker et al. 1990) created for use with the Hubble Space Telescope.

2)~For many objects, secure (ie, confirmed from the literature) classification
as a CV.

3)~A reference to a modern finding chart.

4)~For many objects, a reference to a modern spectrum of the object.

5)~For essentially all objects except novae (which may be found in Duerbeck
1987a), finding charts generated from the Guide Star Survey plate material are
presented in the source reference.

\section {Structure}

\subsection{File Structure}

{\em \cat} 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. Table 1 gives the
characteristics of these files.

{\bf A copy of this document should be transmitted with any additional copy of
this catalog}.

Notes on Table 2
\end{center}

GCVS NAME: the name of the object in the {\em
General~Catalogue~of~Variable~Stars} and subsequent Namelists (67th, Kholopov
et al. 1985; 68th, Kholopov \etal~1987; 69th, Kholopov \etal~1989; 70th,
Kazarovets and Samus 1990). For those objects without variable star designations
(104), we list the constellation name only (which is derived from Roman
[1987]). 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.

COORDINATES: For non-novae, the J2000 coordinates of the objects as measured on
the Space Telescope Guide Star plates. The right ascension is given to the
nearest 0.01s, while the declination is given to the nearest $0\secpoint1$. The
accuracy of the Guide Star Catalog is $0\secpoint4$ in the north and
$0\secpoint6$ in the south (Taff \etal~1990). For the novae the coordinates are
taken from Duerbeck (1987a) or from the literature (for recent novae) and are
precessed to the J2000 equinox. For those objects without available/usable
finding charts (31 objects), coordinates have been obtained from the literature
and are generally given to a lesser accuracy than those objects measured in this
work.

CLASSIFICATION: The type of variability of the object. Table~3 lists the
various types used in this work, which are based on the classification scheme
used in the GCVS. Those types in uppercase letters are taken directly from the
GCVS, while those in lowercase letters have been obtained from the literature
(and were generally in agreement with the GCVS and are presumably more
secure). There are 74 objects in the catalogue designated {\bf NON-CV}, which
are stars that have been previously cataloged as CVs and are included for
completeness; the references for these stars are those papers that refute the
CV nature of the objects. The revised classification is given in the comment
section below.

YEAR OF OUTBURST: The year of outburst (for novae).

MAG.~RANGE: The MAXimum and MINimum magnitudes for the objects. For novae the
primary source is Duerbeck (1987a), while for the non-novae the catalog of
Ritter (1990) is the prime source. When no other references to brightness were
available, the GCVS values were used.

MAG. SYSTEM: See Table 4.

COORD~REF: A code for a reference to the coordinates; Table~5 defines the
codes. An asterisk (*) following the references means that there is a comment
regarding the coordinate measurement. (see below.)

CHART REF: for those objects with charts presented in the source referenced
(i.e.,~the non-novae, 467 objects), a code for the original reference from which
our chart is based. Table~6 defines the codes and includes the numeric code
used in the GCVS and subsequent Namelists. For novae (256 objects) a reference
to the previously published chart in Duerbeck (1987a) is given (except for
recent novae).

SPEC REF: A code for a reference to a published spectrum; Table~7 defines the
codes. A prefix of {\bf S} indicates a spectrum in quiescence (271 objects),
while a prefix of {\bf X} indicates a spectrum in outburst (123 objects); we
were unable to locate spectra for 359 objects. Whenever available, the quiescent
spectrum was chosen for the catalog over an outburst spectrum. A colon (:) after
the reference means that only a description of the spectrum is given in the
reference, that the spectrum is a glass plate tracing, or that the reference to
the spectrum is unconfirmed (only for a few novae in Duerbeck [1987a]).

OTHER NAME: A common alternative (non-GCVS) designation for the object.
