Description:
This catalogue is the only complete list of all known double and
multiple systems (18644) of which at least one component was
identified in the Hipparcos final catalog in July 1997 (Cat. I/239),
including the 2994 systems newly discovered by the satellite, as well
as the 155 new astrometric orbital pairs also discovered by the
satellite (Dommanget, 2000Obs...120..202D 2000Obs...120..202D), and also the 38 new
astrometric binaries components of known systems. It may be considered
as a subset of the CCDM as existing in 1998 of which a first edition
appeared in 1994 (Cat. I/211), and of which a second edition
containing more than 45,000 systems is being prepared for publication.
Consequently, the format of this list is that of the CCDM for which
all information may be found in the introduction of its 1994 published
version (as file I/211/ccdm.doc)
The format of this catalogue is the same as the CCDM (Cat. I/211)

114 A1 --- n_IDS *[*W] Note on IDS designation
115-125 A11 --- IDS Uncorrected Index designation (1976.5)
(equinox 1900) and identification letter;
127-132 I6 --- HIP ? Hipparcos Catalogue (I/239) number
--------------------------------------------------------------------------------
Note on CCDM:
The CCDM number is made with RA(2000) limited to 0.1 minute of time
(HHMMm) and Dec(2000) limited to 1 minute of a degree (+DDMM). Full
details about the construction of the CCDM number are given in the
publication.
Note on Comp:
In one record the sign '?' signs appear (for CCDM 07366-1428)
Note on Note1:
* : orbit in the personal catalogue of J.Dommanget (1982;
partially updated to 1994)
& : orbit in the WDS
Note on Note2: the symbols are:
@ = astrometric binary
% = astrometric binary discovered by Hipparcos
Note on Disc:
New discoverer names are:
HDS = Hipparcos new astrometric binary
KZA = S.M. Kazeza
LYS = L. Louys,
NYS = O. Nys,
ONL = Occultation News Letter
Note on r_dRAs:
The new references are:
47 = ORB (Carte du Ciel)
48 = Bordeaux (Soulie)
81 = HIC (Cat. I/196)
82 = HIP (Cat. I/239)
Note on theta:
The following letters are sometimes used to indicate an approximate
location of the secondary component:
'N' (to the North)
'NF'(to the North and following) (first quadrant)
'F' (following)
'SF'(to the South and following) (second quadrant)
'S' (to the South)
'SP'(to the South and preceding) (third quadrant)
'P' (preceding)
'NP'(to the North and preceding) (fourth quadrant)
Note on pmNote: the symbols are as follows:
*: not the pm from the Index;
@: pm from the HIC;
$: pm = pm(B/A);
#: the pm is quite different from the other components' motion,
but the exact values are not available.
Note on DM, Name2: the codes are as follows:
.0 = BD .6 = AGK2/3
.2 = CD .8 = SAO
.4 = CPD
The suffixes "a" and "b" following some DM designations
appear in place of the dot.
Note on m_HD: the symbols are:
/ = second HD identifier
? = questionable identification
* = possible inversion of HD components
Note on n_IDS:
The * means that the Index number is built for a new component
or system;
The W means that the IDS is a WDS number (i.e. based on J2000
position, whereas the IDS is based on B1900 positions)
