Origin of the objects types :

(Ref) Object type as listed in the reference "Ref"
(acronym) Object type linked to the acronym according to the original reference
() Anterior to 2007, before we can link the objet type to a reference, or given by the CDS team in some particular cases

Syntax of coordinates is : "ra dec (wtype) [error ellipse] quality bibcode" :

ra dec : right ascension and declination (unit and frame defined according to your Output Options)
Grey values are increasing the original precision due to the computation of frame transformations
(wtype) : wavelength class for the origin of the coordinates (Rad, mm, IR, Optical, UV, Xray, Gam)
[error ellipse] : measurement uncertainty, on (ra,dec) if the positional angle is 90 degrees, on (majaxis,minaxis) otherwise (in mas at defined epoch in the original catalogue),
position angle (in degrees North celestial pole to East)
quality : flag of quality
- E ≥ 10"
- D : 1-10" (and some old data)
- C : 0.1-1"
- B : 0.01-0.1" + 2MASS, Tyc
- A : VLBI, Hipparcos
bibcode : bibcode of the coordinates reference

bibcode : bibcode of the coordinates reference

Syntax of proper motions is : "pm-ra pm-dec [error ellipse] quality bibcode"

pm-ra : mu-ra*cos(dec) (expressed in the ICRS system in mas/yr)
pm-dec : mu-dec (expressed in the ICRS system in mas/yr)
[error ellipse] : error major axis and minor axis (in mas), orientation angle (in deg)
quality : flag of quality (A=best quality -> E=worst quality, {� } =unknown quality)
bibcode : bibcode of the proper motion reference

Syntax of radial velocity (or/and redshift) is : "value [error] (wavelength) quality bibcode"

value : radial velocity or/and redshift (Heliocentric frame) according to your Output Options
(redshift may be not displayed if the data value is <0 and the database inside value is a radial velocity)
[error] : error of the corresponding value displayed before
(wavelength) : wavelength range of the measurement : Rad, mm, IR, Opt, UV, Xray, Gam or '∼'(unknown)
quality : flag of quality ( A=best quality -> E=worst quality, {� } =unknown quality)
bibcode : bibcode of the value's origin

Syntax of parallax is : 'value quality [error] bibcode'

value : parallax value
quality : flag of quality (A=best quality -> E=worst quality, {� } =unknown quality)
[error] : mean error
bibcode : bibcode of the parallax reference

Spectral type is made of 3 parts: %coding is composed of 4 parts :

the spectral type, which is made of a temperature class, eventually a luminosity class (roman number) and/or spectral peculiarities;
a quality letter: A=best quality→E=worst quality, {� } =unknown quality %
a quality letter: A=best quality -> E=worst quality, {� } =unknown quality
bibcode : bibcode of the spectral type reference

Syntax of fluxes (or magnitudes) is : "filter-name (System) flux-value [error] quality MultVarFlags bibcode"

filter-name : U, B, V, R, I, G, J, H, K, u, g, r, i, z
(System) : may be AB (default is Vega)
flux-value : value of flux or magnitude
[error] : error value
quality : flag of quality of the flux value ( A=best quality -> E=worst quality, {� } =unknown quality)
MultVarFlags : Mult is zero or one char (J) for joined photometry ; Var can be zero or two chars (V[0-4])
bibcode : bibcode of the flux reference
