PPM-Extended (PPMX) is a catalogue of 18 088 919 stars on the ICRS system containing astrometric and photometric information. Its limiting magnitude is about 15.2 in the GSC...

This services provides 1D spectra from DR5 of LAMOST (Large Sky Area Multi-Object Fiber Spectroscopic Telescope) through SSAP; data is served both in VO-standard SDM and, via...

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...

The RAdial Velocity Experiment (RAVE) contains stellar atmospheric parameters (effective temperature, surface gravity, overall metallicity), radial velocities, chemical...

ARI's "Geschichte des Fixsternhimmels" is an attempt to collect all astrometrically useful observations from before ca. 1970 in a way comparable to what has been done to...

UCAC4 is a compiled, all-sky star catalog covering mainly the 8 to 16 magnitude range in a single bandpass between V and R. Positional errors are about 15 to 20 mas for stars in...

The catalogue ARIHIP has been constructed by selecting the 'best data' for a given star from combinations of HIPPARCOS data with Boss' GC and/or the Tycho-2 catalogue as well as...

This table is a subset of GaiaSource comprising those stars in the Hipparcos and Tycho-2 Catalogues for which a full 5-parameter astrometric solution has been possible in Gaia...

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...

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...

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...

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...

The RAdial Velocity Experiment (RAVE) contains stellar atmospheric parameters (effective temperature, surface gravity, overall metallicity), radial velocities, chemical...

High resolution spectra from the HERMES spectrograph at the Flemish Mercator Telescope, operated by KU Leuven at the Roque de Los Muchachos Observatory on the island of La...
