TheoSSA provides spectral energy distributions based on model
atmosphere calculations. Currently, we serve results obtained using
the Tübingen NLTE Model Atmosphere Package (TMAP) for hot compact
stars.

Description:
This dataset contains spectroscopic observations of 29 globular
clusters in the Magellanic Clouds and the Milky Way performed with
VLT/X-shooter over eight full nights.
A catalogue of 541 nearby (within 10pc of the sun) stars, brown
dwarfs, and confirmed exoplanets in 336 systems, as well 21
candidates, compiled from SIMBAD and several other sources. Where
available, astrometry and photometry from Gaia eDR3 has been inserted.
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`).
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.
