Description:
A proper-motion catalogue of 5080236 stars in 49 OGLE-II Galactic
bulge (GB) fields, covering a range of -11°<l<11° and -6°<b<3°. Some
columns have been left out from the original source.

Description:
This survey gives photometric redshifts of objects within 275 deg²
(−50◦ < α < 60◦ and −1.◦25 < δ < +1.◦25) centered on the Celestial
Equator. Each piece of sky has ∼20 runs of repeated scanning by the
SDSS camera contributing and thus reaches ∼2 mag fainter than the SDSS
single pass data, i.e., to r ∼ 23.5 for galaxies.
The SuperCOSMOS data primarily originate from scans of the UK Schmidt
and Palomar POSS II blue, red and near-IR sky surveys. The ESO Schmidt
R (dec < -17.5) and Palomar POSS-I E (dec > -17.5) surveys have also
been scanned and provide an early (1st) epoch red measurement.
Mirrored here is the source table containing four-plate multi-colour,
multi-epoch data which are merged into a single source catalogue for
general science exploitation. Within the GAVO DC, some column names
have been adapted to local customs (primarily positions, proper
motions).
This standard describes a means to present usage examples for TAP
services in a way that is partially machine readable while primarily
being consumable by humans. It is a complement to the IVOA Table
Access Protocol.
TEUV corrects synthetic stellar fluxes for interstellar absorption
for wavelengths smaller than 91.1 nm. It simulates radiative
bound-free absorption of the ground states of H, He, C, N, and O using
Opacity Project data. Two interstellar components with different
radial and turbulent velocities, temperatures, and column densities
are considered.
This table is a subset of GaiaSource comprising those stars in the
Hipparcos and Tycho-2 Catalogues for which a full 5-parameter
astrometric solution has been possible in Gaia Data Release 1. This is
possible because the early Hipparcos epoch positions break some
degeneracies due to the limited Gaia time coverage. This table
contains a substantial fraction of the around 2.5 million stars in the
Hipparcos and Tycho-2 catalogue. Many stars have been excluded due to
several reasons, such as saturation, cross-match errors or bad
astrometric solution. All rows have Gaia solution id
1635378410781933568.
The tutorial uses VOSA to analyse members of the Collinder 69 open
cluster by crossmatching a given local set of objects and accesses VO
services to crossmatch the objects with 2MASS to receive colors. The
resulting SEDs are analysed using different fit functions.
Within this use case you learn about the constellations of the
Zodiac, i.e. those crossed by the apparent path of the Sun during the
year. Together with some characteristics the orbital motion of the
Earth, in this use case you also find a short excursion into history
of astronomy. The use case also introduces the precession of the
equinoxes.
