Title:: APFS HIP Simple Query
Short Name:: apfs_hipquery
Date:: 23 Mar 2022 13:13:06

Title:: APFS Simple Query Form
Short Name:: apfs_catquery

Title:: ARIGFH identified objects
Short Name:: arigfh scs
Date:: 06 Feb 2024 09:10:44
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.

ID:: ivo://org.gavo.dc/arihip/q/cone
Title:: ARIHIP astrometric catalogue
Short Name:: arihip cone
Date:: 23 Mar 2022 13:13:11
Publisher:: The GAVO DC team
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).

Publisher:: The GAVO DC team
Description:: Computation of Greenwich Apparent Sidereal Time, Greenwich Mean Sidereal Time, and the Earth Rotation Angle

ID:: ivo://org.gavo.dc/ucac3/q/corr
Title:: Corrections between UCAC3 and PPMXL
Short Name:: UCAC3 ICRS corr
Date:: 23 Mar 2022 13:13:19
Publisher:: The GAVO DC team
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.

Title:: Corrections between USNO-B and PPMXL
Short Name:: PPMXL USNO corr
Date:: 23 Mar 2022 13:13:09
Publisher:: The GAVO DC team
Description:: 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 over all stars in a sqrt(2)/2-degrees environment around the gridpoint given. The corrections given here should bring USNO-B based astrometry to the ICRS.
