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 construct the FK* series of
fundamental catalogs. About 7e6 published positions are included.
In GAVO's DC, we provide tables of identified and non-identified stars
together with the master catalog that objects were identified against.

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 the FK6. It provides 'best
data' for 90 842 stars with a typical mean error of 0.89 mas/year
(about a factor of 1.3 better than Hipparcos for this sample of
stars).
This service provides the data for the TGAS catalogue (Tycho-Gaia Astrometric Solution ; a subset of the Gaia DR1 catalogue providing parallaxes and proper motions from Tycho2 for a little more than 2 million sources).
This service provides Gaia data (currently DR1, DR2 and EDR3), with full-sky catalogues of high-precision positions down to about 20 mag, as a mirror of the original ESA archive with extra features (e.g., tables and column metadata).
We present the Arizona CDFS Environment Survey (ACES), a recently completed spectroscopic redshift survey of the Chandra Deep Field-South (CDFS) conducted using the Inamori-Magellan Areal Camera and Spectrograph on the Magellan-Baade telescope. In total, the survey targeted 7277 unique sources down to a limiting magnitude of R_AB_=24.1, yielding 5080 secure redshifts across the ~30'x30' extended CDFS region. The ACES data set delivers a significant increase to both the spatial coverage and the sampling density of the spectroscopic observations in the field. Combined with previously published spectroscopic redshifts, ACES now creates a highly complete survey of the galaxy population at R<23, enabling the local galaxy density (or environment) on relatively small scales (~1Mpc) to be measured at z<1 in one of the most heavily studied and data-rich fields in the sky. Here, we describe the motivation, design and implementation of the survey and present a preliminary redshift and environment catalogue. In addition, we utilize the ACES spectroscopic redshift catalogue to assess the quality of photometric redshifts from both the COMBO-17 and Multiwavelength Survey by Yale-Chile imaging surveys of the CDFS.
