Title:: Digitized First Byurakan Survey (DFBS) Spectra Query Service
Short Name:: DFBS SSAP
Date:: 27 Dec 2024 08:31:13
Publisher:: The GAVO DC team
Description:: The First Byurakan Survey (FBS) is the largest and the first systematic objective prism survey of the extragalactic sky. It covers 17,000 sq.deg. in the Northern sky together with a high galactic latitudes region in the Southern sky. The FBS has been carried out by B.E. Markarian, V.A. Lipovetski and J.A. Stepanian in 1965-1980 with the Byurakan Observatory 102/132/213 cm (40"/52"/84") Schmidt telescope using 1.5 deg. prism. Each FBS plate contains low-dispersion spectra of some 15,000-20,000 objects; the whole survey consists of about 20,000,000 objects.

Title:: EPN-TAP table for MPC Asteroid Orbital Data
Short Name:: MPC asteroids
Date:: 27 Dec 2024 08:31:06
Publisher:: The GAVO DC team
Description:: 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.

Title:: Estimated distances to 1.33 billion stars in Gaia DR2
Short Name:: gdr2dist scs
Date:: 27 Dec 2024 08:31:05
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. .. _accompanying paper: http://www.mpia.de/homes/calj/gdr2_distances.html

Title:: Gaia Data Release 1 (DR1) gaia_source
Date:: 17 Sep 2020 08:07:06
Publisher:: The GAVO DC team
Description:: This table, corresponding to gaia_source of the full DR1, contains the 1.15 billion objects reliably detected in the first 14 months of Gaia observations. It essentially consists of high-precision positions and magnitudes. The TGAS subset (about 2 million objects observed by both Gaia and Hipparcos) has proper motions and parallaxes. Users are advised to beware strong correlations between the astrometric parameters present for some of the less densely observed objects and the inhomogeneous coverage in this first data release (solution id: 1635378410781933568).

ID:: ivo://org.gavo.dc/gaia/q2/dr2epochflux
Title:: Gaia DR2 epoch fluxes
Short Name:: gaia.dr2epochflu
Date:: 27 Dec 2024 08:31:02
Publisher:: The GAVO DC team
Description:: A table of the light curves released with Gaia DR2 (about half a million in total). In each Gaia band (G, BP, RP), we give epochs, fluxes and their errors in arrays. We do not include the quality flags (DR2: “may be safely ignored for many general purpose applications”). You can access them through the associated datalink service if you select source_id. You will usually join this table with gaia.dr2light. We have also removed all entries with NaN observation times; hence, the array lengths in the different bands can be significantly different, and the indices in transit_ids do not always correspond to the indices in the time series. Furthermore, we only give fluxes and their errors here rather than magnitudes. Fluxes can be turned into magnitude using:: mag = -2.5 log10(flux)+zero point, where the zero points assumed for Gaia DR2 are 25.6884±0.0018 in G, 25.3514±0.0014 in BP, and 24.7619±0.0019 in RP (VEGAMAG).

Title:: Gaia DR2-light Cone Search
Short Name:: GDR2light SCS
Date:: 27 Dec 2024 08:31:02
Publisher:: The GAVO DC team
Description:: This schema contains data re-published from the official Gaia mirrors (such as ivo://uni-heidelberg.de/gaia/tap) either to support combining its data with local tables (the various Xlite tables) or to make the data more accessible to VO clients (e.g., epoch fluxes). Other Gaia-related data is found in, among others, the gdr2dist, gdr3mock, gdr3spec, gedr3auto, gedr3dist, gedr3mock, and gedr3spur schemas.

Title:: Gaia DR2 light curves SSA
Short Name:: GDR2 TS SSAP
Date:: 27 Dec 2024 08:31:02
Publisher:: The GAVO DC team
Description:: This service exposes about 0.5 million light curves of stars classified as variable by the Gaia analysis system through the VO SSAP protocol. The lightcurves are published per-band and are also available through obscore.
