Catalogues available @ AIP

The AIP hosts all complete official Gaia datasets: DR1, DR2, EDR3, DR3 and FPR1 as one of the 4 partner data centers, along with the main Gaia archive maintained by ESAC. Additionally, AIP provides auxiliary catalogues for cross match purposes and community contributions.

Gaia Focused Product Release (Gaia FPR)

Gaia's Focused Product Release was released on Tuesday 10 October 2023. The Gaia Focused Product Release builds partly on the data period that went into Gaia's Data Release 3 but in case of the Solar System objects extends the stretch of time that forms the basis for the FPR data product. The five data products together form the Gaia Focused Product Release.

Gaia Data Release 3 (Gaia DR3)

The third data release has been split into two parts: the Early Data Release 3 (Gaia EDR3) was released the 3rd of December 2020. The full Gaia Data Release 3 (Gaia DR3) was released on the 13th of June 2022.

Gaia DR3 provides information on more than 1.8 billion sources, astrometric solutions for more than 1.4 billion sources, radial velocites for more than 33 million sources (4 times more than DR2).

But the most awaited feature of Gaia DR3 is the publication of more than 200 millions BP/RP spectra and about 1 million high resolution spectra from the radial velocity spectroscopy unit (RVS). Finally Gaia DR3 also comes with a huge object classification catalog from about 1.59 billion sources.

Gaia Data Release 2 (Gaia DR2)

The second Gaia data release includes a five-parameter astrometric solution (positions on the sky, parallaxes, and proper motions - for more than 1.3 billion sources, radial velocities for 7.2 million sources, additional 0.36 billion sources with position and mean magnitude. Additionally, epoch astrometry for 14,099 known solar system objects and more sets of special sources.

Gaia Data Release 1 (Gaia DR1)

Gaia DR1 is based on observations collected between 25 July 2014 and 16 September 2015. It publishes informations on more than 1 billion sources, it contains full astrometry for 2 millions of them.

Auxiliary catalogues available at Gaia@AIP

The whole is greater than the sum of its parts. Additional to the official Gaia datasets, AIP hosts catalogues for cross match purposes and community contributions. Please have a look at auxiliary catalogues on Gaia@AIP
