Some tips:

• links are underlined in blue
• select the SOFA mirror site closer to your location for fast service: in France or in Canada
• when available, the corresponding paper is referenced to the ADS Article database
• note that a lot of database presented here are mirrored worldwide. E.g.:
• Simbad is available in France and in US
• Vizier: France, US and Japan
• ADS (articles):

     - Harvard-Smithsonian Center for Astrophysics, Cambridge, US
     - Centre de Données astronomiques de Strasbourg, France
     - European Southern Observatory, Garching, Germany
     - National Astronomical Observatory, Tokyo, Japan
The links shown point towards the "original" site whenever possible
 
• follow the arrow  to go up at the beginning of the page

Publication: a short description (gzipped, 84k) of the SOFA site will appear in the next
                            issue of the Standard Star Newsletter
 

The site is referenced by:

• Christian Nitschelm's homepage (in astronomical links Section)
• Astroweb (NOAO, Virtual Library, SIMBAD, Cambridge, Australie, Calgary, Vilspa, )
• ASPS (Action Spécifique de Physique Stellaire, french organism) database page
• Laboratoire d'Astrophysique de Toulouse et Bagnères in Astronomical links page
• Laboratoire d'Astrophysique de Grenoble in Astronomical links page

Nota Bene : An IAU project is also called SOFA (Standards Of Fundamental Astronomy), and "will provide a collection of definitive astronomical algorithms and standards for use in astronomical computing." It is not related to the present site (I discovered the IAU project lately, I may change the name of my own site if a near futur, if necessity arises).
