Description:
This data set is the machine-readable version of the fourth edition of
the General Catalogue of Variable Stars (Kholopov et al. 1985-1988).
The machine version contains the same data as in the first three
volumes of the printed catalog, but only the data tables without the
textual material (introduction, bibliography, remarks) are included.
Modifications to the format of the machine version have been made at
the Astronomical Data Center in order to effect a completely
homogeneous record structure suitable for full machine processing and
sorting.
The fourth edition of the General Catalogue of Variable Stars
supersedes the third edition (Kukarkin et al. 1969-1970), three
supplements (Kukarkin et al. 1971, 1974, 1976) containing data for
5401 new variable stars and improved data for many earlier designated
variables, and five namelists (62-66) published in the Information
Bulletin of Variable Stars (Kukarkin et al. 1976; Kholopov et al.
1978, 1979, 1981a, 1981b), which included only cross identifications
for 2619 new variables. This new edition contains data for 28484
individual objects discovered and named by 1982 and located mainly in
the Milky Way galaxy. These data are contained in the first three
published volumes. The fourth volume of the fourth edition, published
in 1990, contains a table of all variables ordered by right ascension
and declination (B1950), a table of variables listed by variability
type, and an extensive series of cross-identification tables to
alternate designations (see II/172). The fifth and final volume will
contain data for all presently known variables in external galaxies
(including the Magellanic Clouds), extragalactic supernovae, and
optically variable quasistellar objects and galactic nuclei
(see II/205).
Data contained in the catalog include star identifier, equatorial
position (B1950), annual precession, galactic coordinates, type of
variability, maximum and minimum magnitudes, epoch of maximum, period,
and spectral type.
Since extensive modifications have been made to the record structure
of the machine version, users are encouraged to carefully study the
brief descriptions given in the document.
The list of errors published by Durlevich et al. (1994) has been
incorporated in this version

--------------------------------------------------------------------------------
Note (1): the position (equatorial and galactic) is not listed when the
variable is equivalent to another catalogued variable ('=' in
column Exists, byte 158)
Note (2): Ref1 is "00001" if the main characteristics of the star were
determined by the authors themselves (see details in "adc.doc")
Note (3): If no chart is available for the variable, but the star is
contained in one of the Durchmusterung catalogs, the corresponding
abbreviation (BD, CPD, COD) is given.
Note (4): Code for alternate photometric system of magMin.
Field is non-blank if magMin is a magnitude or amplitude given in
a system other than that indicated by magCode, e.g. "U" or "R".
Note (5): the photometric system in which magMin and magMax are
reported (see also Note (4)). The main codes are P (photographic
magnitudes) and V (visual, photovisual, or Johnson's V).
See details in file "adc.doc"
Note (6): 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.
For novae (types N) and supernovae (types SN), the Epoch is followed
by a year of outburst enclosed in parentheses (bytes 109-114).
Note (7): the following codes are used:
':' epoch is uncertain;
'+' epoch may be later than that reported;
'-' epoch may be earlier than that reported.
Note (8): 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.
Note (9): Modifications made at CDS compared to the
"Selected Astronomical Catalogs, Vol. 1" CD-ROM of ADC (NASA):
Four stars shows a problem in the Period column: UY Dor;
DD Eri, DE Eri and LL Sct has a '+' instead of the decimal point,
the '+' was pushed to the n_Period column
Note (10): 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 (11): the '*' indicates that the duration of the light constancy
phase at minimum light (d) for an eclipsing variable is equal
to zero.
Note (12): the following codes are used:
'=' if the variable is equivalent to another catalogued variable
(the identification of the other variable will be in SpType),
'N' if the object does not exist.
Note (13): the following non-common transliterations of greek letters
are used: dzeta, miu, niu, ksi, khi. Lower- and upper-case
latin letters must be distinguished (e.g. u HER and U HER)
