Title:: A classifier for spurious astrometric solutions in Gaia EDR3
Short Name:: gedr3spur.main
Date:: 27 Dec 2024 08:31:04
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.

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.

Title:: Gaia DR3 Lite Cone Search
Short Name:: DR3 lite Cone
Date:: 27 Dec 2024 08:31:03
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 gdr3mock, gdr3spec, gedr3auto, gedr3dist, gedr3mock, and gedr3spur schemas.

ID:: ivo://org.gavo.dc/gaia/s3/ssa
Title:: Gaia DR3 MC sampled XP spectra SSA
Short Name:: gdr3spec SSAP
Date:: 27 Dec 2024 08:31:12
Publisher:: The GAVO DC team
Description:: This is a re-publication the Gaia DR3 RP/BP spectra in the IVOA Spectral Data Model. It presents the continous spectra in sampled form, using a Monte Carlo scheme to decorrelate errors, elaborated in this resource's reference URL. The underlying tables are also available for querying through TAP, which opens some powerful methods for mass-analysing the data.

Title:: Gaia DR3 source catalogue "light"
Short Name:: gaia.dr3lite
Date:: 27 Dec 2024 08:31:03
Publisher:: The GAVO DC team
Description:: This is gaia_source from the Gaia Data Release 3, stripped to just enough columns to enable basic science (but therefore a bit faster and simpler to deal with than the full gaia_source table). Note that on this server, there is also The gedr3dist.main, which gives distances computed by Bailer-Jones et al. Use these in preference to working with the raw parallaxes. This server also carries the gedr3mock schema containing a simulation of gaia_source based on a state-of-the-art galaxy model, computed by Rybizki et al. The full DR3 is available from numerous places in the VO (in particular from the TAP services ivo://uni-heidelberg.de/gaia/tap and ivo://esavo/gaia/tap).

ID:: ivo://org.gavo.dc/gaia/q2/dr2light
Title:: Gaia DR2 source catalogue "light"
Short Name:: gaia.dr2light
Date:: 27 Dec 2024 08:31:02
Publisher:: The GAVO DC team
Description:: This is a “light” version of the full Gaia DR2 gaia_source table, containing the original astrometric and photmetric columns with just enough additional information to let careful researchers notice when data is becomes uncertain and the full error model should be consulted. The full DR2 is available from numerous places in the VO (in particular from the TAP services ivo://uni-heidelberg.de/gaia/tap and ivo://esavo/gaia/tap). This table also includes a column containing the Renormalized Unit Weight Error RUWE (GAIA-C3-TN-LU-LL-124-01), a robust measure for the consistency of the solution. On this TAP service, there is the table gdr2dist.main containing distances computed by Bailer-Jones et al (:bibcode:`2018AJ....156...58B`). If in doubt, use these instead of the parallaxes provided here.

ID:: ivo://org.gavo.dc/gedr3auto/q/main
Title:: Gaia eDR3 Autocorrelation
Short Name:: gedr3auto.main
Date:: 27 Dec 2024 08:31:05
Publisher:: The GAVO DC team
Description:: This is a table that simply gives, for each object in Gaia eDR3, the identifier of its closest neighbour together with the distance of the pair.
