Description:
We present astrophysical parameters of 220 million stars, based on
Gaia XP spectra and near-infrared photometry from 2MASS and WISE.
Instead of using ab initio stellar models, we develop a data-driven
model of Gaia XP spectra as a function of the stellar parameters, with
a few straightforward built-in physical assumptions. This resource is
a VO re-publication of the resulting catalog of stellar parameters.

This service delivers (most of) the datasets held at
PDS-PPI VO server. In addition to the default (nonstandard)
way of just appending accrefs to the get access URL, there is also a
very simple datalink service here that, for each dataset, essentially
just gives the dataset itself and possibly a preview. More advanced
datalink services might be available.
Some datasets may be embargoed, in which case the access yields a 403.

Description:
Small subset of the SuperCOSMOS Science Archive, useful for testing queries. The SuperCOSMOS data held in the SSA primarily originate from scans of Palomar and UK Schmidt blue, red and near-IR southern sky surveys. The ESO Schmidt R (dec < -17.5) and Palomar POSS-I E (dec > -17.5) surveys have also been scanned and provide a 1st epoch red measurement. Further details on the surveys, the scanning process and the raw parameters extracted can be found on the further information link. The SSA is housed in a relational database running on Microsoft SQL Server 2000. Data are stored in tables which are inter-linked via reference ID numbers. In addition to the astronomical object catalogues these tables also contain information on the plates that were scanned, survey field centres and calibration coefficients. Most user science queries will only need to access the SOURCE table or to a lesser extent the DETECTION table.
The database of Gamma Ray Burst (GRB) photometrical observations
obtained on defferent telescopes at Fesenkov Astrophysical Institute,
Almaty, Kazakhstan. Observations were carried out in the optical
range.
This is a catalogue of photometric redshifts of galaxies in the
Stripe 82 obtained when morphology (galaxy size, ellipticity, Sérsic
index, and surface brightness) are included in training on galaxy
samples from the SDSS and the CFHT Stripe-82 Survey (CS82). Our
redshifts yield a 68th percentile error of 0.058(1 + z), and a outlier
fraction of 5.2 per cent.
This dataset comprises the public data observed by the Pierre Auger
cosmic ray observatory, which is 1% of its total data. It contains
28493 events between 0.1 and 49.7 EeV collected between 2004 and 2013.

Description:
The Planetary web services @ FUB's TAP end point. The Table Access
Protocol (TAP) lets you execute queries against our database tables,
inspect various metadata, and upload your own data. It is thus the
VO's premier way to access public data holdings.
Tables exposed through this endpoint include: columns, groups, key_columns, keys, schemas, tables from the tap_schema schema, epn_core from the hrsc3nd schema, emptyobscore, obscore from the ivoa schema.
