ANNOUNCEMENT
During the past several years, we have made significant changes in the
Washington Double Star databases which we want to bring to your attention:
1. Completion of the 5th Orbit Catalog. This project, begun by Charles Worley
before his untimely death, has now reached a stage where we are making it
available to the public. The Catalog consists of 1261 orbits of 1226
systems. An objective grading of orbits has been made, based on the scale
established by Worley & Heintz in the 4th Catalog. This grading procedure is
thoroughly explained. The orbit catalog also contains more accurate
coordinates and photometry, multiple cross-references, catalog statistics,
notes to individual systems, ephemerides, and GIF files of the orbits (with
all published measures and their respective O-C lines plotted). While the
online version will be continuously updated and maintained, a CD version of
the 5th Catalog is currently being produced. To make sure you are on the
mailing list for this CD, please send your current mailing address to
"bdm@draco.usno.navy.mil" .
2. It has been created a list of systems with well-defined orbits which may be
useful for scale calibration. A link to this list is given in the Fifth
Orbit Catalog.
3. There are also a list of over 6,000 "neglected doubles" - binaries which have
either never been confirmed or not been observed for over 20 years. All
objects are brighter than V=11, with separations > 3. and Delta m < 3.
Three observing lists (northern, equatorial, and southern) are linked to the
WDS website
4. The WDS is larger and more complete than ever. It consists of 84,084 systems
(from 548,816 individual means). This is 7.7% more systems (and 22% more
means) than contained in the WDS 1996.0. Changes include many contributions
from speckle interferometry groups, double star measures from Hipparcos and
Tycho-2, and contributions from the Webb Society. The largest single
collection of data comes from the inclusion of the Washington Fundamental
Catalogs (a collection of 144 astrographic and transit circle catalogs) which
contain over 36,000 double star measures. The online WDS continues to be
updated on a nightly basis.
5. The data request software has been completely re-written and now includes
elements and ephemerides from the 5th Orbit Catalog as well as measures from
the (previously unavailable) Delta-m Catalog. We also can provide custom
made observing lists.
6. The "Double Star Library" (the IAU Commission 26 web page) has moved from
CHARA/GSU to the USNO.
For details on these and other changes (and anticipated changes) in the double
star databases please inspect the main WDS web page:

ANNOUNCEMENT
The Ramon Maria Aller Observatory at the University of Santiago de Compostela,
Spain, has completed its first Catalogue of Orbits and Ephemerides of Visual
Double Stars. At the International Workshop held in Santiago de Compostela in
1996 it was announced that this Catalogue would be heir to the ephemerides
catalogues edited at the Nice Observatory by Muller, Meyer, and Couteau, Morel
and Fulconis; however, it has been extended to include orbits, and now lists
orbits up to the end of the year 2000.
In our orbital selection, it has been our basic criterion to not replace any
early orbit except for those reasonably improved by subsequent one. We believe
that it will make a welcome companion to the USNO 5th Orbit Catalog, of interest
to both Commission 26 members and astronomers in general.
In all, the new Catalogue contains 1545 orbits for 1208 systems. Each binary has
been assigned a letter (A, B or C) indicating its current status as regards the
possibility of calculating a reliable orbit. This classification has been
carried out on the basis of the arc described, the number and nature of the
available observations, and/or whether closely similar orbits have been
calculated independently by different authors. Notes indicate the existence of
other components of the system, whether it is also a spectroscopic binary,
whether it has an astrometric orbit, etc.
The elements of each orbit are accompanied by a reference to the original
publication, the ephemerides will be predicted within the next few years, and
letters indicating such information as the equinox to which the node is referred,
or whether the elements of the orbit as originally published were flawed by
typographical errors. New orbits will be included as they become available.
The Catalogue may be consulted on-line via internet at

ANNOUNCEMENTS
For a variety of reasons, there exist a large subset of measures contained
in the WDS database which have not been published. To make these data
available to the astronomical community we have made them accessible from
the main WDS web page:
http://ad.usno.navy.mil/wds/wdstext.html#unpublished .
It is anticipated that this section will expand substantially as the data
contained in the WDS are collated.
Nils Wieth-Knudsen measures:
In late 2001, Inger Wieth-Knudsen made available to the U.S. Naval
Observatory the original measurement cards Dr. Nils Wieth-Knudsen made
towards the end of his distinguished career. The original cards are
cataloged in the James Melville Gillis Library of the U.S. Naval
Observatory. The 471 measures recorded on these cards are grouped into 211
means of 59 systems, and include 33 measures of differential magnitude. Made
with both 10 and 30 inch telescopes, the observation dates range from
1961.32 to 1989.34 and the measured separations range from 0.46 to 28.97
arcseconds. These measures are accessible at:
http://ad.usno.navy.mil/wds/unpublished/wieth-knudsen.html .
Walt Sanders measures:
Over the past years Walt Sanders has (and is) continuing his observing of
primarily wide M dwarf stars with a filar micrometer on the Lick 36-inch
refractor. This continues the work described in The Astronomical Journal
(vol. 71, p. 1008; December 1966). As of January 1, 2002 it consisted of
219 measures averaged into 99 means of 69 pairs, with observation dates from
1996.32 to 1998.70 (thusfar, observations continue) and the measured
separations range from 3.2 to 122.9. In three cases no separation is
measured, but the position angle is. These measures are accessible at:
http://ad.usno.navy.mil/wds/unpublished/sanders.html .
Also, in what (by some) could be more properly characterized as a labor of
love, a web page has been constructed giving an overview of the history of
double star research at the U.S. Naval Observatory. The history surveys the
three major programs (micrometry, photography, and speckle interferometry)
and also provides numerous pictures, statistics, a discussion of some binary
discoveries, supplementary documents (obituaries, professional summaries,
etc.), and notes to some of the more colorful characters that have been at
the USNO over the years. This web page is:
http://ad.usno.navy.mil/wds/ds_history.html .

"The Tycho Double Star Catalogue"
by
Fabricius, C., Høg, E., Makarov, V.V.,
Mason, B.D., Wycoff, G.L., & Urban, S.E.
I would like to draw your attention to the Tycho Double Star Catalogue,
TDSC, which has just been accepted for publication by A&A, and the
corresponding files will become available from CDS.
Abstract:
We report the discovery of 13251 visual double stars, mostly with
separations between 0.3 and 1 arcsec, from a dedicated re-reduction of the
Tycho data from the star mapper of the ESA Hipparcos satellite. The new
doubles are combined with 18160 WDS systems identified in the Tycho-2
Catalogue, and 1220 new Tycho-2 doubles, to form the Tycho Double Star
Catalogue, TDSC, a catalogue of absolute astrometry and BT, VT photometry
for 66219 components of 32631 double and multiple star systems. We also
include results for 32263 single components for systems unresolved in
TDSC, and a supplement gives Hipparcos and Tycho-1 data for 4777
additional components. The TDS thus contains a total of 103259 entries.
Cross identifications are given to WDS, HD, Hipparcos and Tycho-2.

ANNOUNCEMENT
Changes to the WDS :
The WDS currently consists of 585,254 mean positions of 98,084 systems.
1. Duplicate Discovery Designations Removed:
One of the more difficult issues in dealing with the WDS as a database is the
presence of duplicate discovery designations; that is, different systems
assigned the same 3-character and 4-digit designation. These generally fall
into one of two categories: systems given the same numbers but published in
different lists, and those given some additional designation appended to the
original one.
Examples of the first are the binaries first resolved by W. Herschel and both
F.G.W. Struve and O. Struve. William Herschel published seven lists (I - VI,
plus "new", or N), with stars of each list starting at number 1. In
addition to their original discovery lists, each of the Struve's published an
appendix, as well as a list of "rejected" doubles. These multiple lists
were completely spelled out in the Aitken Double Star Catalogue (e.g., H IV
48), but when the Index (IDS) Catalogue was compiled at Lick all of these
other designators were dropped for lack of space. To uniquely identify a
system then required both the discovery designation and the position. As a
result there are, for example, five components with the designation H 48! The
source Herschel list was given in the notes file to the IDS. Appended and
rejected stars from the lists of the Struve's were handled with an "a"
or "r" towards the end of the WDS data line in most cases.
In the second (and fortunately rare) case, systems found quite near to known
ones were given the same designation plus trailing character(s) (e.g., ES
1293a or BU 885 1/2). Sometimes both components were assigned these
additional characters, sometimes only one; occasionally two pairs in an
entirely different section of the sky were given the same designation by the
author (probably by mistake).
Each of these cases is being handled in a different manner. For the William
Herschel discoveries, a list identifier is added to column three of each
designation. For example:
H 19 (at 16 hours) was originally H II 19 and is now known as H 2 19,
H 7 (at 18 hours) was originally H V 7 and is now known as H 5 7, and
H 111 (at 06 hours) was originally H N 111 and is now known as H N 111.
In the case of the O. Struve appendix an A is added following STT in the
name. For F. Struve, he provided two appendices. Those from the shorter list
(Appendix II) are designated STFB. For example:
STF 11 (appendix I) is now STFA 11.
STF 11 (appendix II) is now STFB 11.
STT 252 (appendix) is now STTA252.
Stars of the second type are given the same 3-letter discovery designation
but a new number, starting with 9001, to indicate that they originally had a
different designation. For example:
BAL2356b is now BAL9001.
BU 885 1/2 is now BU 9001.
A complete list of stars of the second type is provided in the error
correction file. All changes in designation are described in the notes file.
In addition to these, designations for 271 W. Herschel (H ), 110 F. Struve
(STF) and 227 O. Struve (STT) systems have been changed. Note that for some
of these systems, the former three character, four digit reference (a3i4)
has been replaced by a four character, three digit reference (a4i3).
Although, for all USNO applications (e.g., data or observing list request) an
a7 read will see no difference.
2. Arcsecond Precise Coordinates:
Coordinates which are sixty times more precise than the WDS identifier are
now provided for the majority of WDS systems (i.e., tenths of a second of
time and seconds of arc). Coordinates are obtained from Hipparcos, Tycho-2,
the Tycho Double Star Catalogue, or through manual inspection. It is expected
that the next significant improvement in this area will be when either the
2MASS or UCAC data are cross-referenced with the WDS. Incremental changes will
continue to be made as well. The ten-digit WDS identifier is retained and
will continue to be the same for all components in hierarchical systems.
However, the precise coordinate will be for the primary of the subsystem. For
example, in the case of a system made up of A-BC and BC pairs, they will both
have the same ten-digit WDS identifier, however, the fourteen digit precise
coordinate would be of the A and B component, respectively.
So far this matching has been made for 80% of the WDS (i.e., 78,655 systems).
These coordinates are found close to the end of the WDS summary line.
3. Secondary Proper Motions added:
The most common note (N = 1421) in the WDS notes file was the proper motion
of the secondary, when known. The above matching with Tycho-2 has allowed the
determination of secondary proper motion for 37% of the WDS (i.e., 36,042
systems). The secondary proper motion is found following the precise
position. This is expected to grow considerably when the UCAC is complete.

ANNOUNCEMENT
THE CATALOGUE OF THE COMPONENTS OF DOUBLE AND MULTIPLE STARS (CCDM)
(SECOND EDITION - 2002)
A second edition of the CCDM has been released (under reference I-274) at the Centre de
Donnees Astronomiques (CDS) at Strasbourg at the beginning of this year. A full
description is at press in "OBSERVATIONS ET TRAVAUX" n° 54, pp.5-29 (*) - a bulletin of
the SOCIETE ASTRONOMIQUE DE FRANCE - which will come out at the end of september.
This recent edition contains:
* 171 astrometric systems
* 43.753 double systems
* 4.138 triple systems
* 903 quadruple systems
* 360 systems with more than four components
thus a total of nearly 50.000 systems, whereas the first edition published in 1994 -
that served as data base for establishing Annexe 1 of the Hipparcos Input Catalogue (ESA
SP 1136) - contained only 34.031 systems.
We should recall that, as in the case of the first edition, this catalogue gives the
positions of the principal component and - when available - of all other indivual ones
of each system to an acuracy generally better than 1".
It contains all new systems discovered by the satellite and all new components
discovered in known systems.

(*) May be ordered for 9 Euros at the Societe Astronomique de France, 3,
rue Beethoven, F - 75016 PARIS.

IBEROAMERICA LEAGUE OF ASTRONOMY (LIADA) CIRCULAR
Since the Summer of 2001 the Iberoamerica League of Astronomy (LIADA) has a double star
section which is formed only by amateurs. This section is headed by Francisco Rica
(Merida -- Spain --) and has as principal objetives the astrometric realization and
study (relative -- theta and rho -- and absolute -- AR, DEC and proper motions --) and
photometry (JHKBV band) of neglected or unconfirmed visual double stars. Every three
months the results are published in the section's circular in addition to other
specialized journals (Webb Society circulars and The Double Star Observer). The results
will be sent to Brian Mason (USNO) to be included in the WDS catalogue. The first
circular, of 23 pages, was edited in March 2001 and includes the confirmation of 11
double stars, some of them not measured since 1820-1830. Six of the program double
stars could not be confirmed. In astrometry 23 double stars were measured from a total
of 155 individual measures averaged in 43 measurements. For astrometry, photographics
plates were used from DSS and digitized images from 2MASS in addition to a 0.3 m
telescope with CCD. The mean internal errors were 0.2 and 0.07. The B and V band
photometry were made for 13 double stars. A brief study of all measured doubles showed
the suspect physical nature of several of them, and also showed errors in WDS. A
section with news on double stars close this circular.
