Description:
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. This is fully explained for each data product described
below. The five data products together form the Gaia Focused Product
Release.
Gaia Focused Product Release contains:
1. Astrometry and photometry from engineering images taken in the
omega Centauri region
2. The first results of quasars' environment analysis for
gravitational lenses search
3. Extended radial velocity epoch data for Long Period Variables
4. Diffuse Interstellar Bands from aggregated RVS spectra
5. Updated astrometry for Solar System objects.
The pre-main sequence accretion parameters, as initially announced to
be part of the Gaia Focused Product Release, has been postponed to
Gaia's Data Release 4.

Note (1): Photometry processing mode as follows:
0 = "gold" photometric dataset. Sources in this dataset have complete colour
information
1 = "silver" photometric dataset. Sources in this dataset have incomplete
colour information and therefore were calibrated using an iterative
process that estimated the missing colour information from the source
mean G and either BP or RP photometry (depending on which band had full
colour information available) using empirical relationships derived from
the gold dataset.
2 = "bronze" photometric dataset. Sources in this dataset had insufficient
colour information and therefore were calibrated using default colour
information derived from the gold dataset.
16 = this data was not produced with the nominal PhotPipe code, but with a
dedicated photometric overlap calibration performed for SIF CF Focussed
Product Release using calibrated DR3 sources as reference.
