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.

24. Gaia DR3 source catalogue "light"
ID:

Title:
Gaia DR3 source catalogue "light"
Short Name:
gaia.dr3lite
Date:
25 Jun 2024 10:32:03
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).
26. Gaia DR2 source catalogue "light"
ID:

Title:
Gaia DR2 source catalogue "light"
Short Name:
gaia.dr2light
Date:

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.

GALAH survey. FGK binary stars (Traven+, 2020)
Short Name:

Publisher:
CDS
Description:
We here analyse a specific data-set: the extended GALAH dataset. This consists of stellar spectra from the GALAH survey (reduced as explained in Kos et al., 2017MNRAS.464.1259K), apparent magnitudes from a variety of photometric catalogues (AAVSO Photometric All Sky Survey - APASS; Henden et al. 2016, Cat. II/336, Gaia DR2; Gaia Collaboration et al. 2018, Cat. I/345. Two Micron All Sky Survey - 2MASS; Skrutskie et al. 2006, Cat. VII/233, Wide-field Infrared Survey Explorer - WISE; Wright et al. 2010, Cat. II/311), and the parallax measurements from Gaia DR2. The data provided in this catalogue are described in Table A.1 of the paper.
28. Geometric and photogeometric distances to 1.47 billion stars in Gaia Early Data Release 3 (eDR3)

Title:
Geometric and photogeometric distances to 1.47 billion stars in Gaia Early Data Release 3 (eDR3)
Short Name:
gedr3dist.main
Date:
27 Dec 2024 08:31:06
Publisher:
The GAVO DC team
Description:
We estimate the distance from the Sun to sources in Gaia eDR3 that have parallaxes. We provide two types of distance estimate, together with their corresponding asymmetric uncertainties, using Bayesian posterior density functions that we sample for each source. Our prior is based on a detailed model of the 3D spatial, colour, and magnitude distribution of stars in our Galaxy that includes a 3D map of interstellar extinction. The first type of distance estimate is purely geometric, in that it only makes use of the Gaia parallax and parallax uncertainty. This uses a direction-dependent distance prior derived from our Galaxy model. The second type of distance estimate is photogeometric: in addition to parallax it also uses the source's G-band magnitude and BP-RP colour. This type of estimate uses the geometric prior together with a direction-dependent and colour-dependent prior on the absolute magnitude of the star. Our distance estimate and uncertainties are quantiles, so are invariant under logarithmic transformations. This means that our median estimate of the distance can be used to give the median estimate of the distance modulus, and likewise for the uncertainties.

Title:
Hubble Source Catalog Detailed Search
Short Name:
HSC
Date:

Publisher:
Space Telescope Science Institute Archive
Description:
The Hubble Source Catalog (HSC) is designed to optimize science from the Hubble Space Telescope by combining the tens of thousands of visit-based source lists in the Hubble Legacy Archive (HLA) into a single master catalog. The Hubble Source Catalog (HSC) detailed search displays an entry for each separate detection (or nondetection if nothing is found at that position) using all the relevant Hubble observations for a given object (i.e., different filters, detectors, separate visits). The catalog currently contains over 100 million entries.
