Title:: ARIGFH identified objects
Short Name:: arigfh scs
Date:: 27 Dec 2024 08:31:12
Publisher:: The GAVO DC team
Description:: ARI's "Geschichte des Fixsternhimmels" is an attempt to collect all astrometrically useful observations from before ca. 1970 in a way comparable to what has been done to construct the FK* series of fundamental catalogs. About 7e6 published positions are included. In GAVO's DC, we provide tables of identified and non-identified stars together with the master catalog that objects were identified against.

Title:: ARIHIP astrometric catalogue
Short Name:: arihip cone
Date:: 27 Dec 2024 08:31:05
Publisher:: The GAVO DC team
Description:: 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).

ID:: ivo://org.gavo.dc/ucac3/q/corr
Title:: Corrections between UCAC3 and PPMXL
Short Name:: UCAC3 ICRS corr
Date:: 27 Dec 2024 08:31:13
Publisher:: The GAVO DC team
Description:: Differences between UCAC3 and PPMXL in positions and proper motions, on an all-sky one-degree grid. At each gridpoint we give the differences X(PPMXL)- X(UCAC3) averaged over all stars in a sqrt(2)/2-degrees environment around the gridpoint given. The corrections given here should bring UCAC3 based astrometry to the ICRS.

Title:: Corrections between USNO-B and PPMXL
Short Name:: PPMXL USNO corr
Date:: 27 Dec 2024 08:31:04
Publisher:: The GAVO DC team
Description:: Differences between USNO-B and PPMXL in positions and proper motions, on an all-sky one-degree grid. At each gridpoint we give the differences X(PPMXL)- X(USNO-B1.0) averaged over all stars in a sqrt(2)/2-degrees environment around the gridpoint given. The corrections given here should bring USNO-B based astrometry to the ICRS.

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 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.

ID:: ivo://org.gavo.dc/gaia/q2/ssa
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).

Title:: Gaia DR3 Lite Distances Subset Cone Search
Short Name:: DR3 lite+dist
Date:: 27 Dec 2024 08:31:06
Publisher:: The GAVO DC team
Description:: This service returns the most important Gaia DR3 gaia_source columns together with robust geometric and photogeometric distances for the ~1.47 billion objects in Bailer-Jones et al's distance catalogue.

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.
