This is a redacted version of the SDSS DR16 table prepared for VizieR
(V/154/sdss16). It is mainly here to facilitate local matches; for
original SDSS-related research, it is probably better to somewhere
else.
Over VizieR and SDSS, we are keeping most of the per-band values in
arrays to keep the column list manageable. Note that in ADQL, array
indexes are 1-based.
We are trying to orient our column names on SDSS but use underscores
instead of camel-casing (e.g. spec_obj_id instead of SpecObjID), since
mixed-case identifiers in SQL is asking for trouble.
To save space, we do not keep psf-based classifications, per-band
offsets, spectrum metadata, and USNO-related information in this
table. Let the operators know if you need any of that.

SMAKCED Census of Structure in Early-type Dwarf Galaxies
Short Name:

Publisher:
The GAVO DC team
Description:
The Stellar content, MAss and Kinematics of Cluster Early-type Dwarf
galaxies (SMAKCED_) project is a survey of 121 Virgo cluster early type
galaxies. This service publishes deep near-infrared (H band) images
obtained by SMAKCED together with `resulting decompositions`_ and other
properties of the galaxies in the sample.

SP_ACE computes stellar parameters (gravity, temperature) and element
abundances from optical stellar spectra (`sample spectrum`_). It employs
1D stellar atmosphere models in Local Thermodynamic Equilibrium (LTE).
The present service does not offer all the options available for SP_Ace
as documented in `the tutorial`_. All options are available if running
SP_Ace locally (cf. `download page`_).
This service exposes an updated version containing some bug fixes with
respect to the one described in the paper.

An archive of optical and near-infrared spectra of strongly lensed
quasars and the lensing galaxies. The spectra are resolved to about a
few Ångstroms and are flux-calibrated. The spectra resulted from
deblending the lensed images in bidimensional spectra available from
the SSAP service for `ivo://org.gavo.dc/mlqso/q/s

Stripe 82 Photometric Redshifts from SDSS Coadditions
Short Name:
s82 coadd cone
Date:

Publisher:
The GAVO DC team
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).
The Fifth Catalogue of Nearby Stars (CNS5) aims to provide the most
volume-complete sample of stars in the solar neighbourhood. The CNS5
is compiled based on trigonometric parallaxes from Gaia EDR3 and
Hipparcos, and supplemented with astrometric data from Spitzer and
ground-based surveys carried out in the infrared. The CNS5 catalogue
is statistically complete down to 19.7 mag in G-band and 11.8 mag in
W1-band absolute magnitudes, corresponding to a spectral type of L8.
Continuous updates of observational data for nearby stars from all
sources were collected and evaluated. For all known stars in the 25 pc
sphere around the Sun, the best values of positions in space,
velocities, and magnitudes in different filters are presented.
