Publisher:
The GAVO DC team
Description:
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.
2. ARIHIP astrometric catalogue

Description:
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).

5. Chandra Source Catalog
ID:

Title:
Chandra Source Catalog
Short Name:
CSC
Date:

Publisher:
Chandra X-ray Observatory
Description:
The Chandra X-ray Observatory is the U.S. follow-on to the Einstein Observatory and one of NASA"s Great Observatories. Chandra was formerly known as AXAF, the Advanced X-ray Astrophysics Facility, but renamed by NASA in December, 1998. Originally three instruments and a high-resolution mirror carried in one spacecraft, the project was reworked in 1992 and 1993. The Chandra spacecraft carries a high resolution mirror, two imaging detectors, and two sets of transmission gratings. Important Chandra features are: an order of magnitude improvement in spatial resolution, good sensitivity from 0.1 to 10 keV, and the capability for high spectral resolution observations over most of this range. The Chandra Source Catalog (CSC) includes information about X-ray sources detected in observations obtained using the Chandra X-ray Observatory. Release 2.0 of the catalog includes 317,167 point, compact, and extended sources detected in ACIS and HRC-I imaging observations released publicly prior to the end of 2014. Observed source positions and multi-band count rates are reported, as well as numerous derived spatial, photometric, spectral, and temporal calibrated source properties that may be compared with data obtained by other telescopes. Each record includes the best estimates of the properties of a source based on data extracted from all observations in which the source was detected. The Chandra Source Catalog is extracted from the CXC"s Chandra Data Archive (CDA). The CXC should be acknowledged as the source of Chandra data.

The Chandra Source Catalog (CSC) includes information about X-ray sources detected in observations obtained using the Chandra X-ray Observatory. Release 1.1 of the catalog includes about 138,000 point and compact sources with observed spatial extents less than ~30 arcsec detected in a subset of ACIS and HRC-I imaging observations released publicly prior to the end of 2009. Observed source positions and multi-band count rates are reported, as well as numerous derived spatial, photometric, spectral, and temporal calibrated source properties that may be compared with data obtained by other telescopes. Each record includes the best estimates of the properties of a source based on data extracted from all observations in which the source was detected.

Description:
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 all stars in a sqrt(2)/2-degrees environment around the gridpoint given. The corrections given here should bring UCAC3 based astrometry to the ICRS.
