- Corrections between UCAC3 and PPMXL
- Short Name:
- UCAC3 ICRS corr
- Date:
- 23 Mar 2022 13:13:19
- 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.

- 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.

- 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).

- Title:
- Gaia DR2 epoch fluxes
- Short Name:
- gaia.dr2epochflu
- Date:

- 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).

- Gaia DR2-light Cone Search
- Short Name:

- Date:

- 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.

- Publisher:

- 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.

- Short Name:
- gaia.dr3lite
- Date:

- Publisher:
- Xinjiang Astronomical Observatory,CAS
- 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. 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).

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).
