Title:: Parameters of 220 million stars from Gaia BP/RP (XP) spectra
Short Name:: XP ap-pars
Date:: 27 Dec 2024 08:31:01
Publisher:: The GAVO DC team
Description:: We present astrophysical parameters of 220 million stars, based on Gaia XP spectra and near-infrared photometry from 2MASS and WISE. Instead of using ab initio stellar models, we develop a data-driven model of Gaia XP spectra as a function of the stellar parameters, with a few straightforward built-in physical assumptions. This resource is a VO re-publication of the resulting catalog of stellar parameters. For bulk downloads, the covariances, the trained model, and more, see https://zenodo.org/record/7811871.

Title:: SDSS DR16 Selection
Short Name:: sdssdr16 cone
Date:: 27 Dec 2024 08:31:13
Publisher:: The GAVO DC team
Description:: This is a redacted version of the SDSS DR16 table prepared for VizieR (V/154/sdss16). It is mainly here to facilitate local matches; for original SDSS-related research, it is probably better to somewhere else. Over VizieR and SDSS, we are keeping most of the per-band values in arrays to keep the column list manageable. Note that in ADQL, array indexes are 1-based. We are trying to orient our column names on SDSS but use underscores instead of camel-casing (e.g. spec_obj_id instead of SpecObjID), since mixed-case identifiers in SQL is asking for trouble. To save space, we do not keep psf-based classifications, per-band offsets, spectrum metadata, and USNO-related information in this table. Let the operators know if you need any of that.
