gaia focused product release documentation

Gaia Focused Product Release
Focused Product Release 1.1

European Space Agency (ESA)
Gaia Data Processing and Analysis Consortium (DPAC)
(10 October 2023)
Executive summary

The Gaia Focused Product Release presents five data products which showcase a subset of the improvements and new data products expected for Gaia DR4. The FPR data products are based on the Gaia observations collected over the same period as used for Gaia DR3 (except for the astrometry and photometry for ω Centauri and the updated Solar System objects astrometry). These data are products based on new observation modes (astrometry and photometry from full-frame CCD images in selected crowded regions), new data processing pipelines (search for gravitationally lensed quasars, DIBs from aggregated RVS spectra), and they offer a taste of the epoch radial velocities to be publised as part of Gaia DR4. For Solar System objects new astrometry and orbits are presented based on 5.5 years of observations (the period covered by Gaia DR4) which leads to a very significant improvement in the quality of the orbits.

The FPR contents are summarized in Table 1.
