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
or nearly synchronously rotating, magnetized white dwarf
AS = subtype of AM, with a slowly asynchronously rotating, magnetized
white dwarf
BD = secondary star is a brown dwarf
CP = coherent pulsator, contains a coherently pulsating white dwarf
CV = cataclysmic variable of unspecified subtype
DA = non-magnetic direct accretor
DN = dwarf nova
DQ = DQ Her star, contains a non-synchronously rotating, magnetized
white dwarf; usually not seen in X-rays
EG = extragalactic source
ER = ER UMa star = SU UMa star with an extremely short supercycle
GC = source in a globular cluster
GW = contains a pulsating white dwarf of the GW Vir = PG 1159-035 type
IP = intermediate polar, shows coherent X-ray period from a
non-synchronously spinning, magnetized white dwarf; usually a
strong X-ray source
LA = low accretion rate polar (LARP), i.e. a somewhat detached magnetic
CV/pre-CV
N = classical nova
Na = fast nova (decline from max. by 3mag in less than about 100days)
Nb = slow nova (decline from max. by 3mag in more than about 100days)
Nc = extremely slow nova (typical time scale of the decline from
maximum: decades)
NL = nova-like variable
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
SS = supersoft X-ray source; CV with stationary hydrogen burning on
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
UX = UX UMa star, subtype of NL
VY = VY Scl star (anti dwarf nova), subtype of NL
WZ = WZ Sge star = SU UMa star with an extremely long supercycle
ZC = Z Cam star, subtype of DN
ZZ = white dwarf shows ZZ Ceti-type pulsations
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.

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 (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.
