Description:
    This file contains Galactic stars known or suspected to be variable.
    It lists all stars that have an entry in the AAVSO International
    Variable Star Index (VSX; http://www.aavso.org/vsx).

    The database consisted initially of the General Catalogue of Variable
    Stars (GCVS) and the New Catalogue of Suspected Variables (NSV) and
    was then supplemented with a large number of variable star catalogues,
    as well as individual variable star discoveries or variables found in
    the literature. Effort has also been invested to update the entries
    with the latest information regarding position, type and period and to
    remove duplicates. The VSX database is being continually updated and
    maintained.

    For historical reasons some objects outside of the Galaxy have been
    included.

Note (1): To get the VSX URL, add the OID to
     http://www.aavso.org/vsx/index.php?view=detail.top&oid=
Note (2): 0 = Variable, 1 = Suspected variable, 2 = Constant or non-existing

Note (3): The value of the period may be preceded by ">" or "<" if the
     period is a lower or upper limit, respectively, or by a "(" which
     indicates that the period is the mean cycle time of a U Gem or
     recurrent nova (a closing bracket exists in u_Period).

     The value of the period may be followed by the following symbols:
     : = uncertainty flag
     ) = value of the mean cycle for U Gem or recurrent nova
         (the corresponding opening bracket exists in l_Period)
     *N = the real period is likely a multiple of the quoted period
     /N = the period quoted is likely a multiple of the real period
Note (4): Passbands include the following:
     U B V R I   = Johnson broad-band
     J H K L M   = Johnson infra-red (1.2, 1.6, 2.2, 3.5, 5µm)
     Rc Ic       = Cousins' red and infra-red
     u v b y     = Stroemgren intermediate-band
     u'g'r'i'z'  = Sloan (SDSS)
     pg pv bj rf = photographic blue (pg, bj) visual (pv), red (rf)
     w C CR CV   = white (clear); R or V used for comparison star.
     R1          = ROTSE-I (450-1000nm)
     Hp T        = Hipparcos and Tycho (Cat. I/239)
     NUV         = near-UV (Galex)
     H1A H1B     = STEREO mission filter (essentially 600-800nm)
