ARI Database for the Apparent Places of Fundamental Stars

Apparent and intermediate places of fundamental stars are provided by this on-line database ARIAPFS.

The annual booklet "Apparent Places of Fundamental Stars" can be found online at this address (since 2024).

Since 2008 apparent and intermediate places are also available via the link to the German Astrophysical Virtual Observatory (VO), as well as Greenwich Apparent Sidereal Time, Greenwich Mean Sidereal Time and Earth Rotation Angle.

For a short explanation of the content of the various files go to the INTRODUCTION; an outline is given here:

 Tables from 1998 to 1999 for 1535 FK5 stars and Sidereal Time                         ==> ARIAPFS QUERY FORM

 Tables from 2000 to 2023 for  878 FK6 Part I stars + Polaris and Sidereal Time        ==> ARIAPFS QUERY FORM

 Apparent and Intermediate Places for 878 FK6 Part I stars + 3272 FK6 Part III stars   ==> VO COMPLIANT INTERFACE (App. Places FK6)

 Apparent and Intermediate Places for more than 100000 Hipparcos stars                 ==> VO COMPLIANT INTERFACE (App. Places HIP)

 Apparent and Intermediate Places for more than 1.3 billion sources Gaia DR3           ==> VO COMPLIANT INTERFACE (App. Places Gaia DR3)

 Greenwich Apparent Sidereal Time, Greenwich Mean Sid. Time, Earth Rotation Angle      ==> VO COMPLIANT INTERFACE (GAST, GMST, ERA)
