I. INTRODUCTION
------------------

The present fifth (and the last) volume of the 4th Edition of the
General Catalogue of Variable Stars (GCVS) is our first attempt to
collect in a unified form the data for all variable and suspected
variable stars - either members of extragalactic systems or observed in
the direction of such systems due to projection. This GCVS volume, like
all previous GCVS volumes, is published as a book as well as presented
in a computer-readable form. References to all volumes of the present,
4th GCVS edition are given in Section V ("References") of this file.

The present state of data systematization for extragalactic variable
stars is extremely different for different galaxies. For some galaxies,
all data for known variables are presented in a single paper, for other
galaxies such information is scattered in the literature, similar to the
situation with the variables of our Galaxy. For some galaxies, it is
only possible to find in the literature rectangular co-ordinates of
variable stars; for other galaxies, equatorial co-ordinates of different
accuracy are also published. The availability of finding charts also
differs from one galaxy to another.

We attempted to gather in the present volume all extragalactic
variable stars for which it is possible to find in the literature
positional information of reasonable accuracy or to measure positions
anew. Here we turned aside from the practice of GCVS vols. I - III
and, whenever possible, attempted to improve co-ordinates of variables
ourselves, trying to present equatorial co-ordinates with the accuracy
to 0.1 s in right ascension, and to 1" in declination. For the
Andromeda galaxy M 31 we adopted even higher standard accuracy (to 0.01
s in right ascension, and to 0".1 in declination). The co-ordinate
measurements, on photographic charts as well as on original plates, were
done mainly by V.P. Goranskij. During improving co-ordinates, a number
of cases of identity of stars considered in original publications to be
different objects were found (especially in the Magellanic Clouds). We
realize that during identification and positional improvement we have
unavoidably made several mistakes, and we shall be grateful to users
for suggestions and corrections. It was attempted to keep information
complete up to the beginning of 1993.

We have also selected for this catalogue stars showing large scatter
of individual measurements from several publications devoted to photometry
of stars in external galaxies but not announcing variability discoveries
explicitly.

It is to be noted that, as already mentioned in the Introduction to
volume III of the GCVS 4th Edition, we retained the traditional
identification (suggested by the discoverers, [248] - hereafter
references in square brackets are to the file evs_ref) of the
variables Z Tuc - TX Tuc (in the system of names of the GCVS vols. I -
III), situated in the region of the Large Magellanic Cloud, with the
stars of the HV lists. One should remember, however, that this
identification, already characterized as somewhat uncertain in [248], is
in fact not seriously justified at all. In the cases of SS Tuc and TV
Tuc we had to deny these identifications since they led to
contradictions; probably for SS Tuc the paper [248] contains a misprint
in the HV number.

Information on extragalactic variable stars is gathered in two parts.
The first part, the Catalogue of extragalactic variables proper,
contains data on variable stars in galaxies with at least one known
variable. If supernova outbursts have been observed in such a galaxy,
information on supernovae is also included. Information on all
extragalactic supernovae is contained in the Catalogue of supernovae.
If, for a given galaxy, no other type variables are known, then the
Table of supernovae is the only source of information for this galaxy in
volume V. The total number of objects in the Catalogue of extragalactic
variables is 10979, that in the Catalogue of extragalactic supernovae is
984.


II. STRUCTURE OF THE CATALOGUE OF EXTRAGALACTIC VARIABLES
(Files : evs_cat, evs_rem, evs_ref)
-----------------------------------------------------------

The structure of the main Table of the Catalogue of Extragalactic
Variables of volume V (file evs_cat.dat) is in general similar to that
used for main tables in vols. I - III (CDS, II/139/). Variable stars
are arranged within corresponding galaxies. The catalogue begins with
data on variables in the Large Magellanic Cloud, the Small Magellanic
Cloud, large galaxies of Andromeda (M 31) and Triangulum (M 33); then,
other galaxies are arranged in the order of increasing right ascensions
of their centers (equinox 1950.0).

GALAXY CODE - Code identifying the galaxy (see Table 1). This
numbering system begins with 089, the first 88 codes being reserved for
constellations (cf. computer-readable versions of the GCVS volumes
I-III). Note that NGC 1466 is a globular cluster (not a galaxy) between
the LMC and the SMC; we presented it separately, because it is not clear
to which galaxy to attribute its variable stars.

VARIABLE STAR No WITHIN THE GALAXY - Number of the variable star in
the galaxy. If in the literature for the considered galaxy there exist
several different variable star numbering systems, we have introduced
new numbers in the order of increasing right ascension for the equinox
1950.0. But if the variable star numbering system for the galaxy is
practically of general use, we have retained it - if necessary, with
additional numbers ordered by increasing right ascension. (Traditional
numbering system in the Triangulum galaxy M 33 reaches V83 [323];
however, since V79 [323] is identical with V30 [313], we have retained
traditional numeration up to V78, and designated stars V80-V83 from
[323] as V79-V82). Due to last-moment improvements of variable star
positions in M 31, there are several cases in this galaxy of the order
of increasing right ascension being not strictly fulfilled.

VARIABLE STAR DESIGNATION - The name of the variable in the adopted
system of variable star designations: name of the galaxy (see Table 1)
+ "V" + variable star No. within the galaxy (see column VARIABLE STAR No
WITHIN THE GALAXY).

REMARK(S) FLAG - An asterisk (*) following the number shows that
there is a remark for this star (see file evs_rem). The Remarks in
volume V in general follow the pattern of GCVS vols. I-III. Since the
majority of stars in the present volume are faint objects in dense star
fields, it would take too much space in the Remarks to describe the
presence of neighboring stars, so we had to restrict ourselves to the
most necessary comments of this kind. In the magnetic version of the
remarks, Greek letters are reproduced by Latin letters, like "alpha",
"Delta", etc.; the upper case first Latin letter in such constructions
means that the corresponding Greek letter is in upper case.

EQUATORIAL COORDINATES - The star's right ascension and declination
for the equinox 1950.0. In the present computer-readable version, if
the star's coordinates are only roughly known, they are nevertheless
formally presented to one second of time in right ascension (with the
decimal point following) and to one arcsecond in declination (with the
decimal point following). The column following the coordinates, in such
cases, contains a flag indicating the real accuracy. The flag (") means
right ascensions accurate to one second of time and declinations
accurate to one arcsecond; the flag (:) means declinations accurate to
one tenth of an arcminute; the flag (*) means declinations accurate to
one arcminute. For V0474 in the Sculptor system, the listed coordinates
refer to the galaxy's center since the coordinates of the star itself
are unknown - the flag (!).

TYPE OF VARIABILITY - The classification systems corresponds to the
GCVS vols. I-III. In the present volume we introduce one new variable
star type in addition to the classification system described in our
earlier publications. This is the BLBOO type, called after the
prototype star BL Boo = V19 in the globular cluster NGC 5466 and
referring to the so-called "anomalous Cepheids", i.e. stars with periods
characteristic of comparatively long-period RRAB variables, but
considerably brighter by luminosity (in a very probable assumption of
membership in the corresponding galaxy). There is a number of such
stars in dwarf spheroidal galaxies, in the Small Magellanic Cloud. Note
that the wide scale introduction of this type for variable stars of our
Galaxy is restricted because of a reliable independent luminosity
estimate being not available for the majority of stars. The catalogue
of extragalactic variable stars also includes suspected variables. For
such stars this column contains the symbol "var:".

MAXIMUM MAGNITUDE (LIGHT) - The star's magnitude in maximum brightness.
MINIMUM MAGNITUDE (LIGHT) - That in minimum brightness. The majority of
magnitudes in the catalogue are given to one digit after the decimal
point. It shows that they were determined by means of photographic or
visual observations. Photoelectrically or CCD-determined magnitudes are
given, as a rule, to two digits after the decimal point. The column MIN
may contain the variability amplitude instead (in brackets). The symbol
"(" means that the variable is fainter in minimal brightness than the
magnitude value after that symbol; the symbol ")" means that the
variable is brighter in maximal brightness than the value following that
symbol.

MAGNITUDE CODE - The designation of the photometric band. P means
photographic magnitudes, V means visual or photovisual magnitudes as
well as V system magnitudes. In the latter case, they are usually
distinguishable from visual magnitudes by the number of digits after the
decimal point (as a rule, V system magnitudes are based upon
photoelectric or CCD photometry). Letters U, B, R, I, J, H, K, L, M, N,
O, Q mean, as a rule, magnitudes expressed in corresponding systems of
broad-band photometry.

EPOCH JD 24...- The epoch expressed as a date of the Julian period
(JD). For eclipsing and ellipsoidal variables, RV Tau and RS CVn stars,
the catalogue gives epochs of minimum light, and for the rest of
variables, epoch of maximum light. If this rule is not fulfilled,
necessary explanations appear in Remarks. For novae and supernovae,
epochs of maximal brightness in Julian days are presented, followed by
years of outbursts (in brackets).

PERIOD - The variable star's period in days. For U Gem stars and
recurrent novae, this column gives (in brackets) the mean cycle value,
if known.

M-m OR D - The duration of light increase from minimum to maximum
(M-m) for intrinsic variable stars or the eclipse duration (D) for Algol
type variables are expressed in hundredths of the photometric period
for the star in question. An asterisk (*) to the right side of the
column means, for an eclipsing variable, that the duration of the
constant brightness phase in minimum (d) for this star is equal to zero.

SPECTRUM - The spectral type. If there exist several spectral type
determinations for a star, we preferred more recent ones, taking into
account reliability of each determination. We converted symbols "d"
(dwarfs) and "g" (giants) into luminosity classes V and III. If a nova
showed spectral features typical of novae during or after the outburst,
a symbol (NOVA) is given in this column. If the spectrum shows features
characteristic of U Gem variables, this column contains the symbol (UG).
Continuous spectrum is designated "cont", the symbol "e" means emission
spectrum, lower case letters "ea", "eb" in this column stand for "e
alpha", "e beta". For RR Lyrae stars, spectral types from hydrogen
lines are given. A plus sign (+) between two spectral type values means
that spectra of two components of a spectroscopic binary are observed.
Two spectral type values separated with a minus sign (-) mean the range
of spectral type variations in the process of brightness changes.

REFERENCES - References to the literature (the first reference is to
the study of the star, the second one is to the finding chart). The
list of references for vol. V is independent of those in the earlier
Volumes of the Catalogue, and it is to be noted that different lists of
references are to be used for the main Catalogue (see file evs_ref)
and for the Catalogue of supernovae (see file sn_ref).

DESIGNATIONS - The designation of the variable star in the paper
indicated in the first reference to the literature (see above). If the
paper with the finding chart indicated in the second reference uses
another designation, the latter designation is also given.

VARIABLE STAR IDENTIFICATION (GCVS, NSV) - If the star has a
designation in the system of GCVS vols. I-III, or if it enters the NSV
catalogue, the corresponding designation (number) is given.

NON-MEMBER - Symbols "n" or "n:" for nonmembers (possible
nonmembers) of the galaxy in question. For the stars that enter the
GCVS vols. I-III or the NSV catalogue and are not members of the
corresponding galaxy, the present volume gives only the running number,
co-ordinates, the symbol "n", and the GCVS or NSV name.


III. STRUCTURE OF THE CATALOGUE OF EXTRAGALACTIC SUPERNOVAE
(Files : sn_cat, sn_rem, sn_ref)
--------------------------------------------------------------


We have compiled the Catalogue of extragalactic supernovae using the
GCVS card catalogue. We paid attention mainly to positional and
photometric information on stars themselves. The catalogue includes
supernovae that appeared before the end of 1993. To improve information
on parent galaxies, we used in some cases a computer version of the
Third Reference Catalogue of Bright Galaxies by G. de Vaucouleurs, A. de
Vaucouleurs, H.G. Corwin, Jr., R.J. Buta, G. Paturel, P. Fouque, 1991,
New York: Springer and the NASA/IPAC Extragalactic Database (NED) which
is operated by the Jet Propulsion Laboratory, Caltech, under contract
with the National Aeronautics and Space Administration. The catalogue
is arranged in chronological order of the SN designations.

THE SUPERNOVA'S DESIGNATION followed by a question mark (?) refers to
doubtful or insufficiently confirmed supernovae. Sign (-) marks objects
presently rejected as supernovae. If an asterisk (*) follows the
designation, there is a remark for this object. Remarks (see file
sn_rem) indicate other cases of supernova outbursts in the same
galaxy, contain descriptions of behavior for some stars, etc. For
supernovae entering also our catalogue of extragalactic variables, there
may be a reference to Remarks of the catalogue of extragalactic
variables (see file evs_rem).

PARENT GALAXY'S DESIGNATION. Here "N" means NGC catalogue numbers,
"I" refers to the IC catalogue, "U", to the UGC catalogue, "M", to the
MCG catalogue, and "E", to ESO survey lists. The symbol "An" means an
anonymous galaxy (i.e., a galaxy absent in major catalogues of bright
galaxies), and the symbol "Intergal" is for cases when the supernova
cannot be reliably attributed to a particular galaxy and is considered
intergalactic.

EQUATORIAL CO-ORDINATES OF THE PARENT GALAXY (EQUINOX 1950.0) are
given. The standard accuracy of presented coordinates is to 0.1 s in
right ascension and to 1" in declination, but in many cases we had to
give coordinates of lower accuracy. In such cases, the column following
the coordinates contains a flag similar to those described above, in the
section devoted to the Catalogue of extragalactic variables.

GALAXY'S MORPHOLOGICAL TYPE and its INTEGRATED MAGNITUDE taken from
available sources. The integrated magnitude may be followed by a symbol
indicating the photometric band (MAGNITUDE CODE); we preferred B
magnitudes. If the photometric system symbol is missing, the magnitude
is a photographic one.

MAXIMUM MAGNITUDE (LIGHT) OF SN - the supernova's maximum brightness
date and its apparent magnitude in maximum. If a value is followed by
an asterisk (*), it means that the date and/or the magnitude refer not
to the maximum (not covered with observations), but to the EPOCH OF
DISCOVERY or to an isolated observation at high brightness. As a rule,
we did not include information about maxima if it was based on
considerable extrapolation. Lack of photometric band symbol (MAGNITUDE
CODE) indicates photographic magnitudes. If the magnitude is given with
two digits after the decimal point, it is based on photoelectric or CCD
photometry.

The positional information on the supernova itself follows. It
consists in the DISTANCE FROM THE GALAXY'S NUCLEUS TO THE SUPERNOVA in
right ascension and declination, in arcseconds, or immediately in the
SUPERNOVA'S EQUATORIAL CO-ORDINATES FOR THE EQUINOX 1950.0. The
standard accuracy of equatorial co-ordinates is the same as in the case
of parent galaxies. For a number of supernovae, information on
rectangular and on equatorial co-ordinates is not in complete agreement
if we take into account published co-ordinates of parent galaxies. To
remove such contradictions completely, it would be necessary to
determine anew and independently the co-ordinates for supernovae and
their parent galaxies. The equatorial coordinates may also have lower
accuracy flags (see above).

SUPERNOVA'S CLASSIFICATION - The system of classification for
supernovae is being permanently improved; however, we are not able to
extend the application of some recently introduced and already
frequently used types, like I-C, to supernovae discovered in earlier
years. So we have limited ourselves to the use of types I (I-A, I-B)
and II (II-l, II-pl), with possible indications of peculiarities (pec).

NAME OF THE SUPERNOVA'S DISCOVERER is given next. In cases of
several discoverers, we give the name of the first author of the
discovery followed by "+" symbol. As a rule, we did not present
information on independent rediscoveries in the remarks, for the sake of
brevity. The abbreviation "BASST" in this column means that the
supernova was discovered by the Berkeley Automated Supernova Search
Team.

BIBLIOGRAPHIC REFERENCES - three-digit numbers corresponding to the
reference list (sn_ref). The first reference is usually to the
source of photometric information. The second one is to a paper where
the galaxy's photograph with the supernova or a finding chart was
published.
