Abstract:
In current astronomical surveys with ever-increasing data volumes,
automated methods are essential. Objects of known classes from the
literature are necessary to train supervised machine-learning
algorithms and to verify and validate their results.
The primary goal of this work is to provide a comprehensive data set
of known variable objects from the literature that we cross-match with
Gaia DR3 sources, including a large number of variability types and
representatives, in order to cover sky regions and magnitude ranges
relevant to each class in the best way. In addition, non-variable
objects from selected surveys are targeted to probe their variability
in Gaia and possible use as standards. This data set can be the base
for a training set that can be applied to variability detection,
classification, and validation A statistical method that employed
astrometry (position and proper motion) and photometry (mean
magnitude) was applied to selected literature catalogues in order to
identify the correct counterparts of known objects in the Gaia data.
The cross-match strategy was adapted to the properties of each
catalogue, and the verification of results excluded dubious matches.
Our catalogue gathers 7841723 Gaia sources, 1.2 million of which are
non-variable objects and 1.7 million are galaxies, in addition to 4.9
million variable sources. This represents over 100 variability
(sub)types. This data set served the requirements of the Gaia
variability pipeline for its third data release (DR3) from classifier
training to result validation, and it is expected to be a useful
resource for the scientific community that is interested in the
analysis of variability in the Gaia data and other surveys.
Description:
A catalogue of 7841723 Gaia sources derived by cross-matching with
the content of more than 150 literature catalogues with Gaia. In the
catalogue we provide Gaia Source id and literature coordinates along
with their type and period if it is available. Additionally table 8 of
the paper, that contains the overlaps between different superclasses,
is given here.

Note (1): The fields in plural may contain multiple values separated by ";",
thus are regarded as Strings.
Note (2): The field OPos (nongaiacoordinates) contains the coordinates from
all available literature catalogues of each source (see Note 1).
Each coordinate is formed by Right Ascension and Declination joined by "_".
Note (3): The fields RAdeg (primary_ra), DEdeg (primary_dec),
Pers (period) are direct copy from the literature values, therefore not
formatted.
