Catalogue of high-mass X-ray binaries in the Galaxy (4th edition). Liu Q.Z., van Paradijs J., van den Heuvel E.P.J. <Astron. Astrophys. 455, 1165 (2006)> =2006A&A...455.1165L (SIMBAD/NED BibCode)
Name
The X-ray source designation, with a prefix identifying a high-energy
experiment which detected its emission, and a position-based string based on
its 1950 coordinates, unless preceded by a 'J' in which case it is based on
its J2000 coordinates.
Xray_Type
The X-ray type of the high-mass X-ray binary:
P: X-ray pulsar (66). T: Transient X-ray source (62). E: Eclipsing system (9). R: Radio-emitting HMXB (9). C: Cyclotron resonance scattering feature in X-ray spectrum (16). U: Ultra-soft X-ray spectrum (1).These sources include black-hole candidates (BHC); some 'extreme ultra-soft' (EUS) sources may be white dwarfs (WD) on whose surfaces steady nuclear burning is taking place.
RA
The Right Ascension of the source in the selected equinox. This was
given in J2000 coordinates to an accuracy of 0.1 seconds of time (except in
a small number of cases where it was given with either more or less precision)
in the originating table.
Dec
The Declination of the source in the selected equinox. This was
given in J2000 coordinates to an accuracy of 1 arcsecond (except in
a small number of cases where it was given with either more or less precision)
in the originating table.
LII
The Galactic Longitude of the source.
BII
The Galactic Latitude of the source.
Position_Type
The energy range of the observation used for the derivation
of the source position: O: optical; X: X-ray; R: radio; IR: infrared.
Optical_Name
The name or type of the optical counterpart, if known, or more
generic information: 'No.' followed by a number or letter refers to star
number used in the finding chart, while 'star' refers to a star in the finding
chart that has not been assigned a number or letter.
Ref_Optical
Reference codes for the finding chart(s) for the optical
counterpart. The reference code key can be found at
ftp://cdsweb.u-strasbg.fr/cats/J/A+A/455/1165/refs.dat.gz
Vmag_Limit
A limit flag for the V magnitude, where '>' means fainter
than the quoted value.
Vmag
The apparent visual (V) Magnitude of the optical counterpart. If
a range of visual magnitudes is known for a source, this parameter lists
the maximum (brightest) magnitude while the parameter vmag_min lists
the minimum (faintest) magnitude.
Vmag_Min
If a range of visual magnitudes is known for a source, this
parameter lists the minimum (faintest) magnitude, while the parameter
vmag lists the maximum (brightest) magnitude.
Vmag_Flag
A flag for the V magnitude (vmag) which is set to ':' if the
value of vmag is considered uncertain.
BV_Color
The B-V color index of the optical counterpart. If
a range of (B-V) values is known for a source, this parameter lists
the minimum (bluest) value while the parameter bv_color_max
lists the maximum (reddest) value.
BV_Color_Flag
A flag for the B-V Color which is set to ':' if its
value is considered uncertain.
BV_Color_Max
If a range of (B-V) values is known for a source, this
parameter lists the maximum (reddest) value, while the parameter bv_color
lists the minimum (bluest) value.
UB_Color
The U-B color index of the optical counterpart.
Reddening
The interstellar reddening E(B-V) of the optical counterpart.
If a range of E(B-V) values is known for a source, this parameter lists
the minimum value while the parameter reddening_max lists the maximum value.
Reddening_Max
If a range of E(B-V) values is known for a source, this
parameter lists the maximum value while the parameter reddening lists the
minimum value.
Reddening_Flag
A flag for the reddening which is set to ':' if its
value is considered uncertain.
Ref_Photometry
The reference codes for the optical counterpart photometric
information. The reference code key can be found at
ftp://cdsweb.u-strasbg.fr/cats/J/A+A/455/1165/refs.dat.gz
Jmag
The Two Micron All-Sky Survey (2MASS) J (1.25 microns) magnitude
of the optical counterpart.
Hmag_Limit
A limit flag for the 2MASS H magnitude.
Hmag
The Two Micron All-Sky Survey (2MASS) H (1.65 microns) magnitude
of the optical counterpart.
Kmag_Limit
A limit flag for the 2MASS K magnitude.
Kmag
The Two Micron All-Sky Survey (2MASS) Ks (2.17 microns) magnitude
of the optical counterpart.
Fx_Limit
If the value of the X-ray flux (fx) is an upper limit rather
than a detection, this flag is set to '<'.
Fx
The average observed X-ray flux (density) in microJanskies (µJy) in
the 2 - 10 keV energy range, unless (i) a range of X-ray flux (densities) is
known, in which case this parameter contains the minimum observed X-ray flux
(density) and the parameter fx_max contains the maximum observed X-ray flux
(density), or (ii) the observed X-ray flux (density) is known for
a different energy range, as specified by the fx_range parameter.
Notice that 1 uJy = 10-29 erg/s/cm2/Hz = 2.4 10-12 erg/s/cm2/keV.
Fx_Max
If a range of X-ray flux (densities) is known for a source, this
parameter contains the maximum observed X-ray flux (density) and the parameter
fx contains the minimum observed X-ray flux (density).
Fx_Range
This parameter contains the energy range corresponding to
the quoted X-ray flux values (fx and fx_max). If blank, the energy range
should be assumed to be 2 - 10 keV.
Ref_Fx
A reference code(s) for the X-ray flux (density) values.
