Description (Release 7.15):
    Cataclysmic Binaries are semi-detached binaries consisting of a white
    dwarf or a white dwarf precursor primary and a low-mass secondary
    which is filling its critical Roche lobe. The secondary is not
    necessarily unevolved, it may even be a highly evolved star as for
    example in the case of the AM CVn-type stars.

    Low-Mass X-Ray Binaries are semi-detached binaries consisting of
    either a neutron star or a black hole primary, and a low-mass
    secondary which is filling its critical Roche lobe.

    Related Objects are detached binaries consisting of either a white
    dwarf or a white dwarf precursor primary and of a low-mass secondary.
    The secondary may also be a highly evolved star.

    The catalogue lists coordinates, apparent magnitudes, orbital
    parameters, and stellar parameters of the components and other
    characteristic properties of 880 cataclysmic binaries, 98 low-mass
    X-ray binaries and 319 related objects with known or suspected orbital
    periods together with a comprehensive selection of the relevant recent
    literature. In addition the catalogue contains a list of references to
    published finding charts for 1259 of the 1297 objects, and a cross-
    reference list of alias object designations. Literature published
    before 1 July 2010 has, as far as possible, been taken into account.
    Updated information will be provided regularly, currently every six
    months.

    Old editions include catalogue <V/59> (5th edition),
    <V/99> (6th edition) and <V/113> (7th edition);
    the successive versions of the 7th edition are available
    in dedicated subdirectories (v7.00 tp v7.13)

Note (3): Object type coarsely characterised using the following abbreviations:
    AC = AM CVn star, spectrum devoid of hydrogen lines, subtype of NL
    AM = polar = AM Her system, subtype of NL, contains a synchronously

         maximum: decades)

    Nr = recurrent nova
    NS = system showing negative (nodal) superhumps
    PW = precessing white dwarf
    SH = non-SU UMa star showing either permanent or transient positive
         (apsidal) superhumps

         the white dwarf
    SU = SU UMa star, subtype of DN
    SW = SW Sex star, subtype of NL
    UG = dwarf nova of either U Gem or SS Cyg subtype
    UL = ultra-luminous X-ray source

Note (4): Apparent V magnitude at maximum brightness of:
    novae (N,Na,Nb,Nc,Nr) in minimum
    DN    (UG,ZC,SU)      in minimum
    NL    (UX,AC)         in normal state
    NL    (DQ,IP,AM,VY)   in high state.
    SS                    in high state.

Note (5): In case of eclipses magnitude at mideclipse, of:
    novae (N,Na,Nb,Nc,Nr) in minimum
    DN    (UG,ZC,SU)      in minimum
    NL    (UX,AC)         in normal state
    NL    (DQ,IP,AM,VY)   in high state.
    SS                    in high state.

Note (6): Apparent magnitude at maximum brightness of:
    novae (N,Na,Nb,Nc,Nr) in outburst
    DN    (UG,ZC)         in outburst
    DN    (SU)            in normal outburst

    DN    (ZC)            in standstill
    DN    (SU)            in superoutburst
    WZ                    in superoutburst
    NL    (DQ,IP)         in flaring state or outburst
    iNL    (AM, VY)       in low state
    SS                    in low state

Note (8): Time interval between outbursts is defined:
    - for dwarf novae of subtype UG or ZC: the typical time interval
      between two subsequent outbursts;
    - for dwarf novae of subtype SU:
      T1 is the typical time interval between two subsequent normal
         outburst, and
      T2 is the typical time interval between subsequent superoutbursts.

Note (9): the * indicates, in case of object type SU, that the orbital
    period has been estimated from the known superhump period using the
    empirical relation given by B. Stolz and R. Schoembs (1984A&A...132..187S).

Note (10): The second period is, in case of object type:
     DQ or IP: photometric period if it is different from the
         spectroscopic one
     AM: polarization period = spin period of the white dwarf, if it is
         different from the presumed orbital period (subtype AS)
     SU: superhump period, wherever possible, at the beginning of a
         superoutburst
     SH: photometric period, presumably superhump period of either
         permanent or transient superhumps
     NS: photometric period, period of either permanent or transient
         negative superhumps if 2.__Per. < Orb.Per.

Note (11): This additional period is, in case of object type:
    CP: period of coherent pulsation, (transient if f_3.__Per=T)
    DQ: spin period of the white dwarf
    IP: spin period of the white dwarf, usually detected in X-Rays
    SW: probably the spin period of the white dwarf

Note (12): the flag takes the values:
    ':' uncertainty flag
    'T' indicating transient pulsations
    'Q' indicating the occurrence of quasi- periodic oscillations (QPO)
        in objects of type N, DN, NL.

Note (13): This additional period is, in case of object type:
    CP: second period of coherent pulsation, (transient if f_4.__Per=T)
    DQ: additional period, presumably due to reprocessed X-Rays
    IP: additional period, usually seen in the optical and presumably
        due to reprocessed X-Rays

Note (3): the object type is coarsely characterised using
          the following abbreviations:
    AS = atoll source, subtype of the LMXBs
    BH = black hole candidate, subtype of the LMXBs
    BO = X-ray burster with coherent burst oscillations at the neutron
         star spin period
    DC = source with an accretion disc corona, subtype of the LMXBs
    GC = source in a globular cluster
    MQ = microquasar, source of relativistic jets
    NS = system showing negative (nodal) superhumps
    QN = quiescent neutron star LMXB
    RP = primary is also seen as a radio pulsar
    SH = system showing either permanent or transient superhumps
    SS = supersoft X-ray source
    UL = ultra-luminous X-ray source
    XB = X-ray burst source
    XP = X-ray pulsar
    XT = transient X-ray source
    ZS = Z-source, subtype of the LMXBs

Note (4): in case of eclipses magnitude at mideclipse,
          in case of XT in quiescence

Note (5): in case of XL (XB, XT) in outburst

Note (6): the * indicates, in case of object type SU, that the orbital
    period has been estimated from the known superhump period using the
    empirical relation given by B. Stolz and R. Schoembs (1984A&A...132..187S).

Note (1): Catalogue designations involving the equatorial coordinates
          are given in the following format:
   HHMM+DDMM (catalogue acronyms) if the position is given in B1950
              coordinates -- a 'B' is then present in byte 1.
  JHHMM+DDMM (catalogue acronyms) if the position is given in J2000
              coordinates.
         Here HHMM is the truncated right ascension in hours (HH) and
              minutes (MM), DDMM the truncated declination in  degrees (DD)
              and arcminutes (MM), and + the sign of the declination.

Global Notes:

Note (G1): Wherever possible, the designation of the object given in the
    General Catalogue of Variable Stars (Cat. <II/214>) is used here.

Note (G2): The acronyms used in lists are detailed in the last part of
    the file "whoswho.txt"

Note (G3): The number indicates the accuracy of position in seconds of arc.
     If the positional error is larger than 9arcsec, or unknown, this field
     is left blank. The letter [P] indicates an object with a large proper
     motion.

Note (G4): The EB flag means:
    EB= : (blank) no eclipses observed.
    EB=1: 1 eclipse per orbital revolution observed.
    EB=2: 2 eclipses per orbital revolution observed.
    EB=D: periodic eclipse-like dips observed.

Note (G5): The SB flag means:
    SB=1: single-line spectroscopic binary
    SB=2: double-line spectroscopic binary

Note (G6): Spectral types are given in the following format:
    [Spectral class/Luminosity class], where the usual roman numerals for
    the latter are replaced by the corresponding arabic numerals, i.e.
    I = 1, II = 2, III = 3, IV = 4, V = 5, VI = 6.
