Description:
The GCVS is the only reference source on all known variable stars.
This version contains all of the electronically-readable version as
distributed by the Sternberg Astronomical Institute and Institute of
Astronomy (Russian Acad.Sci.), Moscow. It includes the catalog of
variable stars, updated and completed with the seven Name-Lists of
Variables Stars Nos.67-73 (see IBVS No.2681,1985; No.3058,1987;
No.3323,1989; No.3530,1990; No.3840,1993; No.4140,1995; No.4471,1997),
a catalog of suspected variables, a cross-index of variable star
names, a catalog of extragalactic variables, and a catalog of
supernovae.
Introduction:
The present improved electronic version of the GCVS4 Volumes I-V,
combined with Name-Lists of Variable Stars Nos.67-73, are also
available from Sternberg Institute via anonymous ftp to
ftp.sai.msu.su, /pub/groups/cluster/gcvs... and via
http://www.sai.msu.su/groups/cluster/gcvs/ . The information at
this site is regularly updated (corrections of detected mistakes,
improvements of identifications and coordinates, etc.).
gcvs.dat is the combined computer-readable version of the GCVS4 Vols.
I-III (Kholopov et al. 1985-1988) and Name-Lists of Variable Stars
Nos.67-73 (1985IBVS.2681....1K 1985IBVS.2681....1K, 1987IBVS.3058....1K 1987IBVS.3058....1K,
1989IBVS.3323....1K 1989IBVS.3323....1K, 1990IBVS.3530....1K 1990IBVS.3530....1K, 1993IBVS.3840....1K 1993IBVS.3840....1K,
1995IBVS.4140....1K 1995IBVS.4140....1K and 1997IBVS.4471....1K 1997IBVS.4471....1K) published in the system
introduced during the preparation of the 4th GCVS edition. The total
number of designated variable stars has now reached 31918; of them,
3506 stars enter the Name-Lists Nos.67-73. Errors detected in the
printed Volumes I-III and in the Name-Lists were corrected; the file
includes also improved equatorial positions for some variable stars.
crossid.dat contains all variables, including extragalactic variables,
stars from the Name-Lists, and stars suspected of variability since
the compilation of the NSV catalog, ordered by right ascension
(B1950). The authors tried to provide as complete lists as possible
for the stars identified with the catalogues HD, BD, CoD, CPD, BS, ADS
and for the stars with preliminary HV (Harvard Variable) designations.
As for the other catalogues, their task here was more difficult since
they had to rely upon references to source catalogue names made by
variable star researchers; the tables in the present volume reproduce
the materials used in their work, and incompleteness seems to be
unavoidable. Starting with Name-List No.71, the identifications became
more reliable and complete thanks to special effort of the compilers.
The final, fifth volume contains data for variables in external
galaxies (including the Magellanic Clouds) and for extragalactic
supernovae (see evs*.dat and sn*.dat).
All variables in the present data set are arranged in the order
of their names inside constellations. For Name-list stars, the
information follows the format of the Name-Lists, that is, it
includes only coordinates, the variability type, the range of
brightness variations, and references.
The file nsv.dat is a compilation of 14811 stars suspected of
variability and not finally designated as variables prior to 1980. It
is the successor to the "Catalogues of Stars Suspected of Variability"
published in 1951 and 1965 (Kukarkin et al.). Data contained in the
present catalog include positions, magnitudes, variability types,
alternate designations, and references to the literature. The computer
version of NSV contains principally the same data as in the printed
catalog, but only the data table without the textual material
(bibliography, remarks) is included. Necessary corrections were
introduced, as of June, 1997, and coordinates were improved, compared
to the printed version, for about half of the stars in the catalog.
The Sternberg Institute has started preparation of an electronic
release GCVS 4.2 which will contain improved light elements,
classifications etc. along with sufficiently accurate positional
information. The first approach to this project has resulted in
improved equatorial positions (B1950, J2000) for variable stars in the
constellations of Andromeda, Antlia and Apus including the stars from
the GCVS proper plus the stars from the subsequent Name-lists, with a
new standard of positional accuracy, to 1 second of arc (IAU Inform.
Bull. Var. Stars, in preparation). These positions have been
incorporated in the present data set.

Note on Component: designations of components of double/multiple stars:
A,B; 1,2,3 ... (tau 1). Usually only one component of the binary
is variable, but there exist two cases (CE Cas A,B; EQ Peg A,B) when
both components are variable and enter the catalogue as separate lines.
Note on GCVS: traditional transliterations of greek letters
are used. Lower- and upper-case latin letters must be distinguished
(e.g. u Her and U Her).
Note on NoteFlag: see the document by Kholopov et al. (1985-1988).
Note on RAh, RAm, RAs, DE-, DEd, DEm, DEs:
the position is not listed when the variable is equivalent to another
catalogued variable ("=" in column Exists, byte 142).
Note on u_DEs:
the real coordinates accuracy uses the symbols:
(:) means right ascensions accurate to one second of time and
declinations accurate to one tenth of an arcminute;
(*) means declinations accurate to one arcminute.
(') means right ascensions accurate to one minute of time and
declinations accurate to one arcminute.
Note on VarType: type of variability.
The system of variable star classification corresponds to the GCVS4,
with six additions (ZZO, AM, R, BE, LBV, BLBOO) introduced in the
Name-Lists 67- 72 and in the GCVS vol.V (see file "vartype.txt").
Note on n_magMin: Code for alternative photometric system.
Field is non-blank if magMin is a magnitude or amplitude given in a
system other than that indicated by magCode. An asterisk in the
corresponding position means the amplitude measured in white light.
Note on magCode: the photometric system in which magMin and magMax are
reported (see also Note on n_magMax, n_magMin). The main codes are P
(photographic magnitudes) and V (visual, photovisual, or Johnson's V).
See also the documents by Kholopov et al. (1985-1988) or Warren (1989).
Several stars from the 68th Name-List have in these positions "1."
designating the 1.04 micrometer band of the system introduced by
G.W.Lockwood. The designations u,v,b,y refer to the Stroemgren system.
The symbols "I" and "R" mean magnitudes in Cousins' I system.
"g" designates magnitudes in the system of Thuan and Gunn;
"T" stands for broad-band Tycho magnitudes formed from B and V
measurements; "r" are red magnitudes not tied to a particular system.
Note on Epoch, YearNova: Epochs are given for minimum light for all
eclipsing and ellipsoidal variables, as well as for RV Tau and RS CVn
types, and for maximum for all other types. This rule may occasionally
be broken, but this is explained only in the remarks to the catalog,
which are not available in machine-readable form at this time.
The epochs are Julian dates.
For novae (types N) and supernovae (types SN), the Epoch is completed
by a year of outburst in the YearNova column.
Note on q_Epoch: the following codes are used (see also note on Epoch) :
":" epoch is uncertain.
"+" epoch may be later than that reported;
"-" epoch may be earlier than that reported.
Note on l_Period: the following codes are used:
">" or "<" if period is a lower or upper limit, respectively.
"(": the period is the mean cycle time of a U Gem or recurrent nova
(in this case, there is ")" in n_Period column)
Note on n_Period: the following codes are used:
"*N" if the period may be a multiple of the quoted value;
"/N" if the period may be a fraction of the quoted value;
")" - see the note on l_Period.
Note on M-m/D: this column holds the rising time (M-m) of intrinsic
variables, or the duration of the eclipse (D) for eclipsing binaries.
These values help to define the shape of the light curve. The value is
given in percentage of the period of the star.
Note on n_M-m/D: the "*" indicates that the duration of the light
constancy phase at minimum light (d) for an eclipsing variable is equal
to zero.
Note on Ref1, Ref2:
"00001" - if the main characteristics of the star were determined by
the authors themselves.
"00002" - "09148" - Vol. I GCVS (see Kholopov et al., 1985-1988).
"09149" - "09558" - Vol. II GCVS
"09559" - "10200" - Vol. III GCVS
"V 001" - "V 554" - Vol. V GCVS (see file evs_ref.dat)
"67001" - "73381" - Name-Lists Nos.67-73 (see file nl_ref.dat)
If no chart is available for the variable, but the star is contained in
one of the Durchmusterung catalogs or the Hubble Space Telescope Guide
Star Catalog, the corresponding abbreviation (BD, CPD, CoD, GSC) is
given.
Note on Exists: the following codes are used in column Exists:
"N" in byte 142 if the star does not exist.
"=" in byte 142 appears in three cases.
First, it is used if the variable is equivalent to another catalogued
variable. In such case, after the "=" symbol, the alternative name
of the variable follows, and all necessary information on the star is
to be found under that alternative name.
Second, it is used for all variables of the Name-Lists Nos.67-73, it
is followed by the two-digit number of the Name-list and the four-digit
number of the star in the Name-list, and the information for the star
follows the format of the Name-lists (see above).
Third, the "=" symbol may be followed by the star's name in the GCVS
Vol. V (see the file evs_cat.dat).
This means that the star enters also Vol. V, and the
information of Vol. V makes it possible to improve the data of Vols.
I-III. In this case, the symbol "*" in byte 153 means the presence
of remarks in Vol. V; the symbol(s) "n" or "n:" in bytes 154-155
means that the star is nonmember (possible nonmember) of the galaxy
in question.

Note on GalNo: Code identifying the galaxy.
This numbering system begins with 089, the first 88 codes being
reserved for constellations (cf. catalog II/139).
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.
Note on VarNo: 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.
Note on Name: Variable star Designation.
The name of the variable in the adopted system of variable star
designations: name of the galaxy + "V" + variable star No. within the
galaxy (see column VarNo)
Note on RAh, DEd:
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). See column u_DEs
which indicates the real accuracy.
Note on u_DEs:
the real coordinates accuracy uses the symbols:
(") means right ascensions accurate to one second of time and
declinations accurate to one arcsecond;
(:) means declinations accurate to one tenth of an arcminute;
(*) 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.
Note on VarType: type of variability.
The classification systems corresponds to the GCVS vols. I-III
(catalog II/139), with the addition of the new "BLBOO" type, called
after the prototype star BL Boo = NGC 5466 V19 referring to the
so-called "anomalous Cepheids", i.e. stars with periods characteristic
of comparatively long-period RRAB variables, but considerably brighter
by luminosity. There are also suspected variables designated by the
symbol "var:".
Note on l_magMin, magMin, n_magMin:
minMag contains the minimum brightness, or the variability amplitude
instead (in brackets, i.e. l_magMin='(' and n_magMin=')').
(<) means that minMag is an upper limit (light)
Note on magCode: 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.
Note on Epoch, YearNova:
The epoch expressed as Julian Date. 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.
For novae (types N) and supernovae (types SN), the Epoch is completed
by a year of outburst (YearNova column).
Note on l_P, P, l_P, n_P:
For U Gem stars and recurrent novae, the P column gives (in brackets)
the mean cycle value, if known.
Note on M-m/D, n_M-m/D:
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 (*) in n_M-m/D means, for an eclipsing variable,
that the duration of the constant brightness phase in minimum (d) for
this star is equal to zero.
Note on SpType:
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.
Note on nonMem:
Symbols "n" or "n:" for nonmembers (possible nonmembers) of the galaxy
in question. For the stars that enter the GCVS vols. I-III (file
gcvs.dat) or the NSV catalogue (file "nsv.dat") and are not members
of the corresponding galaxy, the present volume gives only the running
number, coordinates, the symbol "n", and the GCVS or NSV name.

In the present version the authors attempted to give Latin
transliterations of Russian-language names of astronomical periodicals
and books. They did not try to unify the Latin spelling of names
with Cyrillic (or other) original forms, but simply tried to reproduce
the Latin transcriptions in the publications referred to. Of course this
may lead to some confusion, hopefully minor. If a paper enters lists of
references of several Name-Lists, it appears several times in the
present version.

Note on NSVLetter:
The letter "A" is present for one star, NSV 10360A,
which is a completely different object from NSV 10360.
Note on NoteFlag1:
See the document by Kukarkin et al.(1982).
There are several data fields that can contain asterisks. These
signify that more complete information will be found in the remarks to
the published catalog. The remarks are, unfortunately, not machine
readable, but they do contain much supplemental information. There,
one will find information covering situations like, e.g.:
1. The discoverer of the light variability is not the author of the
paper cited in the variability reference, or is one of several
authors of the paper cited. In these cases, discoverers' names
are given in italics in original transcriptions of the remarks.
2. The most important additional information about a star, although
the NSV compilers did not intend to present complete
bibliographies for any catalogued stars.
3. Remarks for visual binaries (in parentheses following the number
of a star in the corresponding catalog) giving visual magnitudes
for the individual components A and B, angular separations, and
position angles for faint components (or semimajor axis of a
relative orbit and period of orbital motion). Data for other
components are then given where applicable. (Combined magnitudes
are generally reported in the machine-readable table.)
Note on RAh, RAm, RAs, DE-, DEd, DEm, DEs:
The position is not listed when the variable is equivalent to a GCVS
star (column VarName).
Note on u_DEs:
The actual accuracy of coordinates is indicated with the symbols:
(:) means right ascensions accurate to one second of time and
declinations accurate to one tenth of an arcminute;
(*) means declinations accurate to one arcminute.
Note on VarType: type of variability.
The system of variable star classification corresponds to the GCVS4
(see file "vartype.txt").
Note on magMax, magMin:
Magnitudes are reported to hundredths if the observations are
photoelectric, to tenths or whole magnitudes if they are not. If only
an amplitude has been measured photoelectrically, then the maximum
magnitude is generally given to tenths only and the minimum is reported
to hundredths.
Note on magCode:
The photometric system in which magMin and magMax are
reported (see also Note on n_magMax, n_magMin). The main codes are P
(photographic magnitudes) and V (visual, photovisual, or Johnson's V).
Note on Ref1:
Usually a 6-digit number coding, as a rule, the reference to the
announcement of the discovery of variability. The first two digits
give the year (in the 20th century) when the announcement was
published (blank for the 19th century). The next four digits give the
number in the list of references contained in the published catalog,
which is generally the first publication announcing the possible
variability. The numbers are followed by a letter code in most cases
(byte 57) with the following meanings:
K: the cited paper contains a chart or photograph of the field with
the suspected variable marked.
D: the cited paper does not contain a chart, but the star is
catalogued in one of the Durchmusterungen (DM) (BD,CD,CPD).
Note on Desig:
The identification of the suspected variable in the
paper referenced above. DM numbers are given without a prefix, the
standard naming convention of "The Henry Draper Catalogue" being used
(BD for zones +89 to -22; CD for -23 to -51; CP for -52 to -89).
Some identifications are given by coordinate designations, a 6-digit
number consisting of hours, minutes, and seconds (or tenths of a minute)
of time and degrees of declination with sign included. An asterisk (*)
signifies that a designation is given in the remarks to the published
catalog.
Stars are sometimes designated with numbers from the catalogs of Zinner
(ZI, 1929) and Prager (PR, 1934, 1937) because the original discovery
publications were not available to the NSV compilers. The catalogs of
Zinner and Prager give detailed references to early observations of such
stars.
Note on SpType:
Temperature classes and subclasses only are given.
Most luminosity classes are III to V, but if a star is a supergiant,
more detailed classification information is given in the remarks to the
published catalog. The following symbols are used:
AF A-F
AM Am
AP Ap
BE Be
E emission spectrum
EA e sub alpha
EV variable emission in spectrum
FG F-G
KM K-M
OF Of
PD Pd
T characteristics of T Tauri stars
Note on Ref2:
The coding for the numbers is similar to that used
in the variability references described above, except that there are no
letter codes. These are references to papers containing identification
charts if no charts are given in the papers cited for the variability
references.
Note on VarName:
1) The alternative name of the variable. All necessary information on
the star is to be found under that alternative name, in the gcvs.dat
file.
2) The star's name in the GCVS Vol. V (see the file v.zip, where the
explanation of the designations is also given). In this case, the
symbol "*" in column 89 means the presence of remarks in Vol. V.

Acknowledgement:
The ADC thanks Drs. Samus and Durlevich for providing us with the
up-to-date, machine-readable version of the GCVS and the Name Lists.
This ReadMe is based on the one prepared by them and the four *.txt.
History of the Machine-Readable Catalogs:
This catalogue gathers the files previously numbered
II/139 (GCVS4, vols I-III), II/172 (GCVS4, vol, IV),
II/205 (GCVS4, vol. V), II/140 (New Suspected Variables), and
II/195 (Name-Lists).
Catalogues II/139 and II/140 were first documented by Warren
(1988, 1989); the documentation for the catalogues II/172 and
II/205 was prepared by N.N. Samus and O.V. Durlevich (Moscow),
with F. Ochsenbein (CDS).
The first version of this Combined Catalogue (September 1997) was
prepared by N. Roman (ADC) with the help of N.N. Samus and O.V.
Durlevich (Moscow).
The second version of this Combined Catalogue (August 1998), which
incorporates the 73rd Name-List of Variable Stars and improved
equatorial positions in Andromeda, Antlia and Apus, was prepared by
N.N. Samus and O.V. Durlevich. Files were slightly reformatted at CDS
(F. Ochsenbein) to have searchable epochs.
The version 1.2 of the file "crossid.dat" was included on 22 May 1999.
A further correction (QW Nor = NSV 7374 instead of NSV 7334) was applied
on 16-Jun-1999 at CDS (message from N.N. Samus to F. Ochsenbein)
