AAVSO Photometric All-Sky Survey (APASS), underway since 2010,
covers the entire sky from 7.5 < V < 16.5 magnitude, and in the BVugrizY
bandpasses. A northern and a southern site are used, each with twin ASA
20cm astrographs and Apogee Aspen CG16m cameras, covering 2.9x2.9 square
degrees with 2.6arcsec pixels. Landolt and SDSS standards are used for
all-sky solutions, with typical 0.02mag calibration errors on the bright
end.
Data Release 10 is a complete reprocessing of all 500K images taken with
the system, including hundreds of nights not part of DR9. Sextractor is
used for star finding and centroiding; DAOPHOT is used for aperture
photometry; the astrometry.net plate-solving library is used for basic
astrometry, supplanted with more precise WCS that utilizes knowledge of the
optical train distortions. With these changes, DR10 includes many more
stars than prior releases.

A Catalog of Galaxies in the Direction of the Perseus Cluster
Short Name:
pcc cone
Date:

Publisher:
The GAVO DC team
Description:
This is a catalog of 5437 morphologically classified sources in the
direction of the Perseus galaxy cluster core, among them 496
early-type low-mass galaxy candidates. The catalog is primarily based
on V-band imaging data acquired with the William Herschel Telescope.
Additionally, we used archival Subaru multiband imaging data in order
to measure aperture colors and to perform a morphological
classification. The catalog reaches its 50 per cent completeness limit
at an absolute V-band luminosity of -12 mag and a V-band surface
brightness of 26 mag arcsec^-2 .
In addition to the published table, this service also contains cutout
images of the objects investigated.
A classifier for spurious astrometric solutions in Gaia EDR3
Short Name:
gedr3spur.main
Date:

Publisher:
The GAVO DC team
Description:
This table contains estimates of the "fidelity" of Gaia eDR3
astrometric solutions, a measure of the likelihood the eDR3 solution
is physical rather than spurious obtained using a neural network
trained on a small, hand-selected sample.
2007-2012 ANTARES search for cosmic neutrino point sources
Short Name:
antares cone
Date:

Publisher:
The GAVO DC team
Description:
A time integrated search for point sources of cosmic neutrinos was
performed using the data collected from January 2007 to November 2012
by the ANTARES neutrino telescope. This dataset includes a total of
5921 events obtained during the effective livetime of 1338 days.
2007-2010 ANTARES search for cosmic neutrino point sources
Short Name:
antares10 cone

Publisher:
The GAVO DC team
Description:
A time integrated search for point sources of cosmic neutrinos was
performed using the data collected from January 2007 to November 2010
by the ANTARES neutrino telescope. This dataset includes a total of
3058 events obtained during the effective livetime of 813 days.
This is legacy data. The most recently released data can be found at
ivo://org.gavo.dc/antares/q/cone.
The catalogue ARIHIP has been constructed by selecting the 'best
data' for a given star from combinations of HIPPARCOS data with Boss'
GC and/or the Tycho-2 catalogue as well as the FK6. It provides 'best
data' for 90 842 stars with a typical mean error of 0.89 mas/year
(about a factor of 1.3 better than Hipparcos for this sample of
stars).

The EPN-TAP 2.0 version of the 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.
Estimated distances to 1.33 billion stars in Gaia DR2
Short Name:
gdr2dist scs
Date:

Publisher:
The GAVO DC team
Description:
This catalogue provides distances estimates (and uncertainties therein)
for 1.33 billion stars over the whole sky brighter than about G=20.7.
These have been estimated using the parallaxes (and their uncertainties)
from Gaia DR2. A Bayesian procedure was used involving a prior
with a single parameter L(l,b), which varies smoothly with Galactic
longitude and latitude according to a Galaxy model. The posterior is
summarized with a point estimate (usually the mode) and a confidence
interval (usually the 68% highest density interval). The estimation
procedure is described in detail in the `accompanying paper`_,
which also analyses the catalogue content.
