Abstract:
Our scientific goal is to provide revised membership lists of the
alpha Per, Pleiades, and Praesepe clusters exploiting the second data
release of Gaia and produce five-dimensional maps (α, δ,
π, µαcosδ, µδ) of these clusters.
We implemented the kinematic method combined with the statistical
treatment of parallaxes and proper motions to identify astrometric
member candidates of three of the most nearby and best studied open
clusters in the sky.
We cross-correlated the Gaia catalogue with large-scale public surveys
to complement the astrometry of Gaia with multi-band photometry from
the optical to the mid-infrared. We identified 517, 1248, and 721 bona
fide astrometric member candidates inside the tidal radius of alpha
Per, the Pleiades, and Praesepe, respectively. We cross-matched our
final samples with catalogues from previous surveys to address the
level of completeness. We update the main physical properties of the
clusters, including mean distance and velocity, as well as core,
half-mass, and tidal radii. We infer updated ages from the white dwarf
members of the Pleiades and Praesepe. We derive the luminosity and
mass functions of the three clusters and compare them to the field
mass function. We compute the positions in space of all member
candidates in the three regions to investigate their distribution in
space.
We provide updated distances and kinematics for the three clusters. We
identify a list of members in the alpha Per, Pleiades, and Praesepe
clusters from the most massive stars all the way down to the
hydrogen-burning limit with a higher confidence and better astrometry
than previous studies. We produce complete 5D maps of stellar and
substellar bona fide members in these three regions. The photometric
sequences derived in several colour-magnitude diagrams represent
benchmark cluster sequences at ages from 90 to 600Myr. We note the
presence of a stream around the Pleiades cluster extending up to 40 pc
from the cluster centre.
Description:
Catalogue of all kinematic candidate members in the Alpha Persei,
Pleiades, and Praesepe open clusters from Gaia DR2 located within
three times the tidal radius of each cluster. We provide positions,
astrometry, photometry from Gaia DR2 complemented with photometry from
several large-scale surveys (2MASS, PanStarrs, UKIDSS, WISE, Sloan).

Global notes:
Note (G1): Result flag as follows:
0 = failed estimate (r_est, r_lo, r_hi are all NaN)
1 = rest is the mode (highest if the posterior is bimodal);
brest/Brest define the lower/upper limits of the highest density
interval (HDI) containing 68% of the posterior probability
2 = rest is the median; brest/Brest define the lower/upper limits of the
equal-tailed interval (ETI), containing 68% of the posterior probability
Note (G2): Combined masses are :
Combined masses at 90Myr for alpha Per,
combined masses at 100Myr for Pleaides and
combined masses at 600Myr for Praesepe.
