Title:: The HSOY Catalog
Short Name:: HSOY SCS
Date:: 27 Dec 2024 08:31:06
Publisher:: The GAVO DC team
Description:: HSOY is a catalog of 583'001'653 objects with precise astrometry based on PPMXL and Gaia DR1. Typical formal errors at mean epoch in proper motion are below 1 mas/yr for objects brighter than 10 mag, and about 5 mas/yr at the faint end (about 20 mag). South of -30 degrees, astrometry is significantly worse. HSOY also contains, where available, USNO-B, Gaia, and 2MASS photometry. HSOY's positions and proper motions are given for epoch J2000. The catalog becomes severely incomplete faintwards of 16 mag in the G-band. The mean epochs are typically very close to Gaia's J2015. HSOY still contains about 0.7% spurious close "binaries" (non-matched stars) from the original USNO-B (marked with non-NULL clone). Also, failed matches within Gaia DR1 contribute another 1.5% spurious pairs (marked with non-NULL comp). In both cases, astrometry presumably is sub-standard.

Title:: The Lepine-Shara Catalog of High Proper Motion Stars
Short Name:: lspm.main
Date:: 27 Dec 2024 08:31:06
Publisher:: The GAVO DC team
Description:: The LSPM catalog is a comprehensive list of 61,977 stars north of the J2000 celestial equator that have proper motions larger than 0.15"/yr (local-background-stars frame). Positions are given with an accuracy of <~100 mas at the 2000.0 epoch, and absolute proper motions are given with an accuracy of ~8 mas/yr. The catalog is estimated to be over 99% complete at high Galactic latitudes (|b|>15{deg}) and over 90% complete at low Galactic latitudes (|b|>15{deg}), down to a magnitude.

Title:: The LIFE Target Star Database LIFETD
Date:: 12 Dec 2024 09:53:20
Publisher:: The GAVO DC team
Description:: The LIFE Target Star Database contains information useful for the planned `LIFE mission`_ (mid-ir, nulling interferometer in space). It characterizes possible target systems including information about stellar, planetary and disk properties. The data itself is mainly a collection from different other catalogs. Note that LIFE's target database is living data. The content – and to some extent even structure – of these tables may change at any time without prior warning. .. _LIFE mission: https://life-space-mission.com/

Title:: The 2MASS point source catalog
Short Name:: twomass.data
Date:: 27 Dec 2024 08:31:04
Publisher:: The GAVO DC team
Description:: The 2MASS Point Source Catalogue, short a couple of exotic fields. We provide this data mainly for matching with other catalogs within our TAP service.

Title:: The PPMXL Catalog
Short Name:: GAVO PPMXL
Date:: 27 Dec 2024 08:31:04
Publisher:: The GAVO DC team
Description:: PPMXL is a catalog of positions, proper motions, 2MASS- and optical photometry of 900 million stars and galaxies, aiming to be complete down to about V=20 full-sky. It is the result of a re-reduction of USNO-B1 together with 2MASS to the ICRS as represented by PPMX. This service additionally provides improved proper motions computed according to Vickers et al, 2016 (:bibcode:`2016AJ....151...99V`).

Title:: The Sixth Fundamental Catalogue (FK6)
Date:: 06 Feb 2024 08:59:18
Publisher:: The GAVO DC team
Description:: Parts I and III of the sixth fundamental catalog, a catalog of high-precision astrometry for bright stars combining centuries of ground-based observations as reflected in FK5 with HIPPARCOS astrometry. The result contains, in particular for the proper motions, statistically significant improvements of the Hipparcos data und represents a system of unprecedented accuracy for these 4150 fundamental stars. The typical mean error in pm is 0.35 mas/year for 878 basic stars, and 0.59 mas/year for the sample of the 3272 additional stars.

Title:: Yale/San Juan SPM4 Catalog
Short Name:: SPM4 CS
Date:: 27 Dec 2024 08:31:02
Publisher:: The GAVO DC team
Description:: The SPM4 Catalog contains absolute proper motions, celestial coordinates, and B,V photometry for 103,319,647 stars and galaxies between the south celestial pole and -20 degrees declination. The catalog is roughly complete to V=17.5. It is based on photographic and CCD observations taken with the Yale Southern Observatory's double-astrograph at Cesco Observatory in El Leoncito, Argentina.
