Description (Release 7.24; final edition):
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 1429 cataclysmic binaries, 108 low-mass
X-ray binaries and 619 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 2035 of the 2156
objects, and a cross-reference list of alias object designations.
Literature published before 1 July 2016 has, as far as possible, been
taken into account.
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 to v7.20)

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
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
LI = low-accretion rate intermediate polar (LARIP), i.e. a somewhat
detached magnetic CV/pre-CV
N = classical nova
Na = fast nova (decline from max. by 3 mag. in less than about 100 days)
Nb = slow nova (decline from max. by 3 mag. in more than about 100 days)
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

Note (4): Apparent 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 (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 and WZ:
T1 is the typical time interval between two subsequent normal outbursts
T2 is the typical time interval between two subsequent superoutbursts
Note (9): the * indicates, in case of object type SU or SH that the orbital
period has been estimated from the known superhump period using the empirical
relation given by Stolz & Schoembs (1984A&A...132..187S 1984A&A...132..187S).
Note (10): The second period, 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 super-outburst
SH: photometric period, superhump period of either permanent or transient
superhumps if 2.Per > Orb.Per
NS: photometric period, period of either permanent or transient negative
superhumps if 2.Per. < Orb.Per

CP: period of coherent pulsation, (transient if f3.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): Flag T indicating transient pulsations
Note (13): Additional period in the system, in case of object type:
CP: second period of coherent pulsation
DQ: additional period, presumably due to reprocessed X-Rays
IP: additional period, usually seen in the optical and presumably due to
reprocessed X-Rays

(old position (J2000): 05 46 48.3 -71 09 24), according to SIMBAD
(from reference 2011AcA....61..103G 2011AcA....61..103G) and the XMM image corresponding

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:
(blank) = no eclipses observed.
1 = 1 eclipse per orbital revolution observed.
2 = 2 eclipses per orbital revolution observed.
D = periodic eclipse-like dips observed.
Note (G5): The SB flag means:
1 = single-line spectroscopic binary
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.
