The LOFAR Two Meter Sky Survey LoTSS DR2
(:bibcode:`2022A&A...659A...1S`) obtained radio data from 27% of the
northern sky between 120 and 168 MHz in the year 2014 through 2020. This
service publishes polarization spectra of extragalactic radio sources
(radio galaxies and blazars) and the rotation measures derived from them.
We also give redshifts for all sources. The data has a spatial resolution
of 20 arcsec.
A catalogue of E(V-I) extinction values is presented for 3174 (LMC)
and 693 (SMC) fields within the Magellanic Clouds. The extinction
values were computed by determining the (V-I) colour difference of the
red clump from Optical Gravitational Microlensing Experiment (OGLE
III) observations in the V and I bands and theoretical values for
unreddend red clump colours.
The MAGIC project observes the VHE sky (GeV~TeV) through Cherenkov
radiation events. The project is operating since 2004 and with the
support from the Spain-VO team they provide data access through a
VO-SSAP and web services. This service re-publishes the data with
homogeneized in flux units (given here in 'erg/(s.cm2)'). Photon
energy values in are transfomred to frequencies.
Reduced frames of lensed quasar observations from Maidanak
Observatory. See the referenceURL for details on the reduction
procedure and calibration data.
The 2MASS Point Source Catalogue, short a couple of exotic fields. We
provide this data mainly for matching with other catalogs within our
TAP service.
Complete Asteroid Data from the Minor Planet Center (MPC),
updated once per month. The MPC operates at the Smithsonian Astrophysical
Observatory under the auspices of Division III of the International
Astronomical Union (IAU).
The MPC Orbit database contains orbital elements of minor
planets that have been published in the Minor Planet Circulars,
the Minor Planet Orbit Supplement and the Minor Planet
Electronic Circulars.
MWSC presents a list of 3006 Milky Way Stellar Clusters (MWSC), found
in the 2MAst (2MASS with Astrometry) catalogue. The target list was
compiled on the basis of present-day lists of open, globular and
candidate clusters. For confirmed clusters we determined a homogeneous
set of astrophysical parameters such as membership, angular radii of
the main morphological parts, mean cluster proper motions, distances,
reddenings, ages, tidal parameters, and sometimes radial velocities.
MWSC-e14a ("MWSC extension 2014a") is a catalogue of
139 new open clusters at high Galactic latitudes
(\|b\|>20 deg) including lists of candidate members. It extends the
Kharchenko et al. 'Catalog of Milky Way Star Clusters'.
The target list was compiled as density enhancements found in the 2MASS
point source catalogue. For confirmed clusters we determined a homogeneous
set of astrophysical parameters such as membership, angular radii of the
main morphological parts, proper motion, distance, reddening, age, and
tidal parameters.
