Title:: AAVSO Photometric All Sky Survey (APASS) DR10
Short Name:: APASS DR10 cone
Date:: 23 Mar 2022 13:13:11
Publisher:: The GAVO DC team
Description:: AAVSO Photometric All-Sky Survey (APASS), underway since 2010, covers the entire sky from 7.5 < V < 16.5 magnitude, and in the BVugrizY bandpasses. A northern and a southern site are used, each with twin ASA 20cm astrographs and Apogee Aspen CG16m cameras, covering 2.9x2.9 square degrees with 2.6arcsec pixels. Landolt and SDSS standards are used for all-sky solutions, with typical 0.02mag calibration errors on the bright end. Data Release 10 is a complete reprocessing of all 500K images taken with the system, including hundreds of nights not part of DR9. Sextractor is used for star finding and centroiding; DAOPHOT is used for aperture photometry; the astrometry.net plate-solving library is used for basic astrometry, supplanted with more precise WCS that utilizes knowledge of the optical train distortions. With these changes, DR10 includes many more stars than prior releases. More information is available at http://www.aavso.org/apass.

Title:: Estimated distances to 1.33 billion stars in Gaia DR2
Short Name:: gdr2dist scs
Date:: 04 Apr 2022 15:48:41
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 DR3 Lite Distances Subset Cone Search
Short Name:: DR3 lite+dist
Date:: 29 Aug 2022 10:46:03

Title:: OpenNGC
Short Name:: openNGC
Date:: 13 Dec 2023 14:11:42
Publisher:: The GAVO DC team
Description:: OpenNGC is a database containing positions and main data of NGC (New General Catalogue) and IC (Index Catalogue) objects. It has been built by merging data from NED, HyperLEDA, SIMBAD, and several databases available at HEASARC. In this VO publication, we have changed most of the column names, mostly to make them work as ADQL column names without resorting to delimited identifiers. The mapping should be obvious.
