Abstract:
The relevance of M dwarfs in the search for potentially habitable
Earth-size planets has grown significantly in the last years. In our
on-going effort of comprehensively and accurately characterising
confirmed and potential planet-hosting M dwarfs, in particular for
the CARMENES survey, we have carried out a comprehensive multi-band
photometric analysis involving spectral energy distributions,
luminosities, absolute magnitudes, colours, and spectral types, from
which we have derived basic astrophysical parameters. We have
carefully compiled photometry in 20 passbands from the far-ultraviolet
to the mi-infrared, and combined it with the latest parallactic
distances and close-multiplicity information, mostly from Gaia DR2, of
a sample of 2479 K5 V to L8 stars and ultracool dwarfs, including 2210
nearby, bright, M dwarfs. For that, we have made extensive use of
Virtual Observatory tools. We have homogeneously computed accurate
bolometric luminosities, effective temperatures of 1843 single
stars, derived their radii and masses, studied the impact of
metallicity, and compared our results with the literature. The over 40
000 individually-inspected magnitudes, together with the basic data
and derived parameters of the stars, one by one and averaged by
spectral type, have been made public to the astronomical community. In
addition, we have reported 40 new close multiple systems and
candidates (rho<3.3-arcsec) and 36 overluminous stars that are
assigned to young Galactic populations. In the new era of exoplanet
searches around M dwarfs via transit (e.g., TESS, PLATO) and radial
velocity (e.g., CARMENES, NIRPS+HARPS), this work is of fundamental
importance for stellar and, thus, planetary parameter determination.
Description:
Astrometric and photometric parameters for 2479 late-type dwarfs and
ultra-cool objects, from K5V to L8.0, collected from several ground-
and space- based surveys, with a wavelength coverage from the
far-ultraviolet to the mid-infrared. Additional astrophysical
parameters (luminosities, effective temperatures, surface gravities,
radii and masses) are provided for a sub-sample of single stars with
measured parallactic distances. Quality flags and booleans indices are
included to help defining well behaved photometric and astrometric data
for each application.

Note (1): For the M and L dwarfs, the identifier "JHHMMm+DDdAAA" is used, plus
"N", "S", "E" or "W" if two stars (in a close binary system) have the same
"HHMMm+DDd" string. For the K dwarfs, the SUPERBLINK catalogue identifier
(Lepine & Shara 2020AJ....159...30H 2020AJ....159...30H; Lepine et al., 2013, Cat. J/AJ/145/102)
is used. For the ultracool dwarfs,we tabulate the Gaia UltraCool Dwarf
Catalogue identifier (Smart et al. 2017, Cat. J/MNRAS/469/301,
2019MNRAS.485.4423S 2019MNRAS.485.4423S).
Note (2): Equatorial coordinates at epoch J2015.5 in equinox J2000.
Note (3): SpTnum=-2.0 for K5V, -1.0 for K7V, 0.0 for M0.0V, 0.5 for M0.5V,
..., 10.0 for L0.0, 10.5 for L0.5, etc.
Note (4): BT-Settl CIFIST grid of synthetic spectra uncertainties are 50 K for
Teff (25K for Teff≤2400K) and 0.5dex for logg.
Note (5): The radii are calculated from Lbol and Teff using the
Stefan-Boltzmann law. The masses are derived from the radii, using the
radius-mass relation for eclipsing binaries by Schweitzer et al.,
2019, Cat. J/A+A/625/A68.
Note (6): In all cases, quality flags are as follows:
true = for poor photometric quality,
false = for good or acceptable photometric quality.
For 2MASS and WISE/ AllWISEphotometry, the alphabetic quality flags
(of the form NNN and NNNN, respectively) are provided.
In the Gaia DR2 data, the indicators 'RUWE' and 'photbprpexcessfactor'
determine the quality of their astrometric and photometric solution.
Note (7): Uncertainties in Gaia DR2 BP, G and RP magnitudes are computed from
the associated bolometric flux and its error.
Note (8): WISE W1W2W3W4 magnitude reference as follows:
WISE = AllWISE (Cutri et al., 2014, Cat. II/328)
WISE*' = WISE (Cutri et al., 2012, Cat. II/311)
Note (9): The second Gaia DR2 identifier is provided for physically bound
binary systems or candidates, separated less than 5 arcsec.
