Bayer
Bayer designation.

BV_Color
B-V Color: Mean color in the standard Johnson UBVRI system for the
hot/cool component respectively. If no slash, /, is given, then the combined
color (outside eclipse) is listed. Values in brackets, [ ], are assumed from
the spectral type versus color relations of Johnson (1966) [ARA&A 4, 193],
FitzGerald (1970) [A&A 4, 34], or Schmidt-Kaler (1982) [in:
Landolt-Boernstein,Vol. 2b, p.1]. An asterisk, *, means that this entry is
measured in the Kron-Cousins UBV(RI)KC system. For transformation to the
standard Johnson system, ee, e.g., Bessell (1979) [PASP 91, 589]. Colors in
brackets, "[ ]", are assumed from the spectral classification. Slash, "/",
always separates values for the hot/cool component, respectively. Braces, "{
}", denote the close binary in a spectroscopic triple system. A color with an
asterisk, "*", in front is measured in the Kron-Cousins RI system. All other
values are in the Johnson UBVRI system. "const" in the "Delta Vave" column
means that photometry has been obtained but no spot wave has been observed.
CaII_Emission
CaII H&K emission. Singly ionized calsium H and K emission. This contains
information on the strength of the emission as well as to which component the
emission belongs. Absolute emission-line surface fulxes are given, if
available, in the Notes field. cool = the cooler component is the emitter, hot
= the hotter component is the emitter, both = both components show H and K
emission. Class a, B, C, D, and (E) = emission strength after Hearnshaw's
scale. IK = 5,4, 3, (2) = strength of the K-emission line in terms of Wilson's
eye-estimated intensities on a scale from 0 (no) to 5 (strong) emission.
Class
BROWSE classification type. The classification is based on the `Spect Type`
parameter, using, in the event of multiple values in that field, the first
value offered.
Conj_Component
The component behind the conjunction.
Conj_Date
Heliocentric Julian date of conjunction -2400000 with the (presumed)
hotter star behind. If the star is not an eclipsing binary, then we
have computed Tconj either from the time of periastron passage or, if
e = 0, from the time of quadrature in order to simulate primary eclipse.
Dec_1950
Declination in 1950 coordinates
Dec
The Declination of the object.
Delta_V
Maximum amplitude of the "wave" in V passband, due to spots, not ellipticity
or reflection. CONST means that photometry has been obtained but no wave
has been observed.
Distance
Distance in parsecs. If no reference is given, then the value has been
computed from the absolute visual magnitude already given in the
catalog. No interstellar absorption was taken into account. A value in
brackets, [ ], has been computed from an M(V) value itself in brackets,
as explained below. Used in calculating W Coords.
DM_Number
Durchmeusterung Identification.
Eccentricity
Eccentricity.
Eclipse
Type of eclipse. It means: NONE = Not eclipsing, TOT = complete
(total/annular) eclipses, PRTL = partial eclipses, YES = an eclipse has
been observed, but it is not known if partial or total, PSBL = it is
possible that eclipses take place but further observations are
necessary to confirm it.
Flamsteed
Flamsteed name.
Halpha
Balmer Halpha line behaviour. abs. = "normal" absorption, em. = emission above
the continuum, fld-in abs. = absorption profile "filled-in" with (presumably)
chromospheric emission, strong abs. = strong absorption profile, mod. abs. =
moderate absorption (this terminology is taken whenever an author used it but
is equivalent to "filled-in abs."), wk abs. = weakly filled-in absorption
profile (in these cases the degree of "filling-in" is not obviously visible by
visual inspection but significant when a standard star spectrum is subtracted).
flares = Hff flare has been observed. For further explanation, the original
reference should be examined.
HD_Number
HD/HDE identification.
HR_Number
HR number.
IAU_Archive
File in the IAU Commission No. 27 "Archive of Unpublished observations of
Variable Stars" (Breger 1985, PASP 97, 85; Breger, Jaschek, Dubois 1990, IBVS
3422).
Inclination
Inclination of the pole of the orbital plane or of the rotation axis, in
degrees.
IUE_Archive
Observed with IUE, possible through March 21, 1990.
LII
The galactic longitude of the object.
Mag_Type
Magnitude type.
Masses
Mass in solar units of the hot/cool component respectively. A blank
indicates that (m sin3 i) is listed, and "f(m)" indicates that the
mass-function is given. If both stars have the same spectral class,
then the more massive star is listed first. If both stars have the same
mass, then the larger star is listed first.
Name
Designation by which the source is most commonly identified. Alternate names
are also included in other fields within the database.
Omega
Longitude of periastron in degrees.
Orbital_Period
Orbital period in days.
Orbital_Variability
Orbital period variability. More quantitative results in terms of (dlnP/dt)
are given in the Notes. Y = yes, N = No.
Photo_Period
Photometric (= rotation) period, in days, derived from the light curve.
Rotation periods from (v sin i) measurements are not included. If "(orb)" is
given, then the photometric period is nearly the same as the orbital period in
File 4. Sometimes we have computed Pphtm from the wave migration period using
the relation 1/Pmigr = 1/Pphtm - 1/Porb; if so, we have mentioned that in the
individual notes. Due to the inherently irregular behaviour of large starspot
groups, the photometric period in all spotted stars is intrinsically variable!
Proper_Motion_Dec
Proper Motion in Dec.
Proper_Motion_RA
Proper motion in RA
RA_1950
Right Ascension in 1950 coordinates
RA
The Right Ascension of the object.
Radii
Radius in solar units of the hot/cool component respectively. A " "
indicates that (R sin i) is listed. Same convention as found in masses
for cases of identical spectral class or equal mass: if both stars have
the same spectral class, then the more massive star is listed first. If
both stars have the same mass, then the larger star is listed first.
