Description:
    The GCVS is the  only reference  source on  all known  variable stars.
    This  version  contains   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 Name-Lists of Variables
    Stars  Nos.  67-79,  the NSV (New catalog of Suspected Variable stars)
    and Supplement to the NSV  stars,   and  a  catalog  of  extragalactic
    variables.   A cross-index makes possible  to find out identifications
    between the GCVS and the NSV catalogue.

Introduction:
    The present improved electronic version of the GCVS4 Volumes I-V,
    combined with Name-Lists of Variable Stars Nos.67-79 and NSV catalogue
    and supplement
    is also available from Sternberg Institute of Moscow University,
    or http://www.sai.msu.su/gcvs/gcvs/

    gcvs_cat.dat is the combined computer-readable version of the GCVS4.2
    Vols. I-III (Kholopov et al. 1985-1988) and Name-Lists of Variable
    Stars Nos.67-79 published in the system introduced during the
    preparation of the 4th GCVS edition; the stars are arranged in the
    order of their names inside constellations. The total number of
    designated variable stars has now reached 41638. Errors detected in
    the printed Volumes I-III and in the Name-Lists were corrected; the
    file includes also improved positional information, light elements,
    classifications etc.

    crossid.dat corresponds to Vol. IV of the GCVS4, and contains all
    variables, including extragalactic variables, stars from the
    Name-Lists, and stars suspected of variability since the compilation
    of the NSV catalog and its supplement. 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; a list of the
    catalogues mentioned is included in the file "abbrev.txt".

    The final, Volume V (extragalactic variable stars) contains 10979
    variable stars in 35 stellar systems (including the Magellanic Clouds,
    the large galaxies in Andromeda and Triangulum, etc., see evs*.dat).

Note (1): 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 (2):
    the position is not listed when the variable is equivalent to another
    catalogued variable (see column VarName)

Note (3):
    the asterisk (*) means that the coordinates that could not be improved
    were recalculated from old rough coordinates to the equinox J2000.0
    with allowance for precession.

Note (4): the following codes are used:
    ":" are used if the epoch is uncertain;
    "+" epoch may be later than that reported;
    "-" epoch may be earlier than that reported.

Note (5):
    ">" or "<" if period is a lower or upper limit, respectively.
    "(" indicates that the period is the mean cycle time of a U Gem
        or recurrent nova (a closing bracket exists in u_Period)

Note (6): the codes are:
  "*N" if the period may be a multiple of the quoted value;
  "/N" if the period may be a fraction of the quoted value;
   ")" closing bracket of l_Period for U Gem-type or recurrent novae.

Note (7): Besides "N", the codes are:
   "=" if the star is also known under another variable name
   "+" if the star is in other catalogues (e.g. Hipparcos or Name Lists)

Note (1):
    The letter "A" is present for one star, NSV 10360A, which is a
    completely different object from NSV 10360.

Note (2):
   The position is not listed when the variable is equivalent to a GCVS
   star (see column VarName).

Note (3):
    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 (4):
    "st" indicates that a light amplitude is reported for the minimum
    and is given in steps (instrumental measure).

Note (5): (empty in the NSV Supplement part):
    identification of the suspected variable in the paper referenced in
    Ref1. DM numbers are given without 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). Identifications
    are sometimes made of coordinates, 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.

Note (6):
  HD spectral types are generally in brackets, e.g. (A0).
  Some special symbols are used:
       AF  for  A-F stars
       FG  for  F-G stars
       KM  for  K-M stars

Note (1): Number of the variable star.
    This numbering system is made of a 3-digit number identifying the
    galaxy, followed by a 4-digit number identifying the variable in the
    galaxy. The numbering system for galaxies begins with 089, the first
    88 codes being reserved for constellations (cf. column "VarNum" in
    file "gcvs_cat.dat")

    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 (3): 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 (4):
    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 (5):
    Symbols "n" or "n:" for "nonmembers" or "possible nonmembers" of the
    galaxy in question. For the stars that enter the GCVS vols. I-III
    (file gcvs_cat.dat) or the NSV catalogue (file "nsv_cat.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.

Global Notes:
Note (G1): Designation of Variable stars (GCVS Name).
    Traditional transliterations of Greek letters are used. Lower- and
    upper-case latin letters must be distinguished (e.g. u Her and U Her).
    See also the file "constel.txt" which gives details about GCVS names
    and conversion to numeric values.

Note (G2): Accuracy of positions use the following symbols:
  "  = right ascensions accurate to one second of time and
      declinations accurate to one arcsecond;
  : = right ascensions accurate to one second of time and
      declinations accurate to one tenth of an arcminute;
  * = declinations accurate to one arcminute.
  ' = right ascensions accurate to one minute of time and
      declinations accurate to one arcminute.
  ! = indicates that the listed coordinates refer to the galaxy's
      center since the coordinates of the star itself are unknown
      (concerns V0474 in the Sculptor system)

Note (G3): The symbols are:
  ">" to indicate a faint limit
  "<" to indicate a bright limit
  "(" to indicate a that the value represents an amplitude

Note (G4): Code for photometric system.
    The main codes are p (photographic magnitudes) and V (visual,
    photovisual, or Johnson's V). Several stars from the 68th Name-List
    have in these positions "1." designating the 1.04 {mu}m band of the
    system introduced by G.W.Lockwood. The designations u,v,b,y refer to
    the Stroemgren system. The symbols "Ic" and "Rc" 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. An asterisk in the corresponding position means a measurement
    in white light.

Note (G5):
    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 as explained
    only in the remarks to the catalog.

Note (G6):
    (M-m) or (D) values help to define the shape of the light curve,
    expressed as a percentage of the period of the variable:
    -- duration of the eclipse (D) for eclipsing binaries;
    -- duration of the rising time (m-M) for intrinsic variables.
    An asterisk (*) in the column "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.
    A colon (:) denotes a poor precision.

Note (G7):
    All references are detailed in the file "refs.dat".
    Numeric references are from Vol. I of GCVS (range 00002-09148),
    Vol. II (range 09149-09558), Vol. III (range 09559-10200), or
    from the Name-Lists (range 67001-77229). References from Vol. V
    (extragalactic variables) start by the letter "V", and references to
    the Suspected variables start by "n" (first part) or "s" (supplement).
    References may also be abbreviation to catalogues (BD, CPD, CoD, GSC,
    HIP, USNO).

Note (G8): an alternative name may contain:
  * a GCVS name (file "gcvs_dat.dat")
  * a "Name-list" number if it starts by the two-digit number 67 to 77,
    and is followed by the four-digit number of the star in the
    corresponding Name-list.
  * the designation of an extragalactic variable (GCVS Vol. V, see file
    "evs_cat.dat"). The name may be followed by an asterisk (*) which
    means the presence of remarks in Vol. V.
