Abstract:
Gaia's readout window strategy is challenged by very dense fields in
the sky. Therefore, in addition to standard Gaia observations, full
Sky Mapper (SM) images were recorded for nine selected regions in the
sky. A new software pipeline exploits these Service Interface Function
(SIF) images of crowded fields (CFs), making use of the availability
of the full two-dimensional (2D) information. This new pipeline
produced half a million additional Gaia sources in the region of the
omega Centauri (ω Cen) cluster, which are published with this
Focused Product Release. We discuss the dedicated SIF CF data
reduction pipeline, validate its data products, and introduce their
Gaia archive table.
Our aim is to improve the completeness of the Gaia source inventory in
a very dense region in the sky, ω Cen.
An adapted version of Gaia's Source Detection and Image Parameter
Determination software located sources in the 2D SIF CF images. These
source detections were clustered and assigned to new SIF CF or
existing Gaia sources by Gaia s cross-match software. For the new
sources, astrometry was calculated using the Astrometric Global
Iterative Solution software, and photometry was obtained in the Gaia
DR3 reference system. We validated the results by comparing them to
the public Gaia DR3 catalogue and external Hubble Space Telescope
data.
With this Focused Product Release, 526 587 new sources have been added
to the Gaia catalogue in ω Cen. Apart from positions and
brightnesses, the additional catalogue contains parallaxes and proper
motions, but no meaningful colour information. While SIF CF source
parameters generally have a lower precision than nominal Gaia sources,
in the cluster centre they increase the depth of the combined
catalogue by three magnitudes and improve the source density by a
factor of ten.
This first SIF CF data publication already adds great value to the
Gaia catalogue. It demonstrates what to expect for the fourth Gaia
catalogue, which will contain additional sources for all nine SIF CF
regions.
Description:
Although the initial plan was to exclude from Gaia Focused Product
Release (FPR) all sources within 160mas from known DR3 sources, it
turned out that in 379 cases this requirement was not fulfilled. The
reasons are explained in the paper. Here we provide a list of these
pairs, together with the reason for this match to appear. For this
match, we shifted DR3 sources to 2017.5 (SIF epoch) positions using
their proper motions.
List of matches between Gaia SIF CF and DR3 sources within 160mas.
