Until recently, SIMBAD
users were asked to cover, at least partly,
the cost of the resources involved in the database service.
This support is now done through sponsorship agreements
negociated with major
national and international agencies as described below.
For the Web access, the former control by IP address has now been
suppressed, so that all users can access Simbad
through the Web without userid/password.
The remote login (tty) access to simbad
still requires the usage of a userid/password.
Non-Web users will have to use ssh (`secure shell') rather than
Please contact the CDS staff if you are in the (rare) situation requiring
a userid and password.
Institutional sponsorship to SIMBAD access
SIMBAD and the CDS are funded by the French governmental agency
INSU (Institut National des Sciences de l'Univers),
CNRS (Centre National de la Recherche Scientifique),
CNES (the French space agency),
and Université Louis Pasteur, Strasbourg.
User access to SIMBAD is sponsored by several national
and international agencies
from Europe, the United States, Canada, and Japan,
as detailed below.
Users from ESO or ESA member states
Starting January 1995, SIMBAD access for
all bona fide scientists affiliated
to astronomical research institutions in
ESA member states,
is sponsored by ESO and ESA.
This results from an agreement signed by
CDS, ESO and ST-ECF,
stating that the charges related to the use of the SIMBAD
database by European users are being payed as a yearly lump
sum jointly by ESO and ESA.
SIMBAD access for U.S. users is sponsored by NASA
(National Aeronautics and Space Administration).
Furthermore, the database may be accessed in the United States
via the Smithsonian Atrophysical Observatory,
where a gateway to SIMBAD is maintained under contract with NASA.
Potential users should contact the
U.S. Simbad gateway at:
SIMBAD access for Canadian users is sponsored through an agreement with
the Canadian Astronomy Data Center. Users should contact
Dr. Daniel Durand at CADC (email@example.com).
SIMBAD access for Japan users is sponsored through an
agreement with ADAC, NAOJ. Details are given in
SIMBAD service page, in Japanese.
The SIMBAD service is no more invoiced to the users.
Potential users can use without restriction the
