Title:: ALHAMBRA Final Catalogue
Short Name:: ALHAMBRA
Date:: 03 Jun 2020 15:33:39
Publisher:: SVO CAB
Description:: This data server provides access to the ALHAMBRA Final Catalogue. The ALHAMBRA (Advance Large Homogeneous Area Medium Band Redshift Astronomical) survey (Moles et al. 2008) has observed 8 different regions of the sky, including sections of the COSMOS, DEEP2, ELAIS, GOODS-N, SDSS and Groth fields using a new photometric system with 20 contiguous, non-overlapping, equal width (~ 300A) filters, covering the optical range (3500A-9700A), plus the standard broadband NIR J, H and Ks filters. The observations were carried out with the Calar Alto (CAHA) 3.5m telescope using the wide field, 0.25 deg2 FOV optical camera LAICA and the NIR instrument Omega-2000. The ALHAMBRA survey dataset represents a ~700hrs of total exposure time, gathered in between the 2005 and 2012.Further information on the project can be found at the ALHAMBRA web page.

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.

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).

ID:: ivo://svo.cab/cmc15
Title:: CMC15, Carlsberg Meridian Catalogue
Short Name:: CMC15
Date:: 03 Jun 2020 15:34:50
Publisher:: SVO CAB
Description:: CMC15 is an astrometric and photometric catalogue of more than 122.7 million stars in the magnitude range 9 < r' (SDSS) < 17. With a positional accuracy to about 35 mas, the catalogue covers the declination range -40deg to 50deg. The current release comprises all the observations made between March 1999 and March 2011. The catalogue fills the gap between 5h 30m and 10h 30m for declinations south of -15deg of the CMC14 and adds the bans -30deg to -40deg. Some zones north of -30deg have also been re-observed in order to improve their internal errors.

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.

Title:: Gaia Data Release 1 (DR1) gaia_source
Date:: 17 Sep 2020 08:07:06
Publisher:: The GAVO DC team
Description:: This table, corresponding to gaia_source of the full DR1, contains the 1.15 billion objects reliably detected in the first 14 months of Gaia observations. It essentially consists of high-precision positions and magnitudes. The TGAS subset (about 2 million objects observed by both Gaia and Hipparcos) has proper motions and parallaxes. Users are advised to beware strong correlations between the astrometric parameters present for some of the less densely observed objects and the inhomogeneous coverage in this first data release (solution id: 1635378410781933568).

ID:: ivo://org.gavo.dc/gaia/q2/dr2epochflux
Title:: Gaia DR2 epoch fluxes
Short Name:: gaia.dr2epochflu
Date:: 23 Mar 2022 13:13:05
Publisher:: The GAVO DC team
Description:: A table of the light curves released with Gaia DR2 (about half a million in total). In each Gaia band (G, BP, RP), we give epochs, fluxes and their errors in arrays. We do not include the quality flags (DR2: “may be safely ignored for many general purpose applications”). You can access them through the associated datalink service if you select source_id. You will usually join this table with gaia.dr2light. We have also removed all entries with NaN observation times; hence, the array lengths in the different bands can be significantly different, and the indices in transit_ids do not always correspond to the indices in the time series. Furthermore, we only give fluxes and their errors here rather than magnitudes. Fluxes can be turned into magnitude using:: mag = -2.5 log10(flux)+zero point, where the zero points assumed for Gaia DR2 are 25.6884±0.0018 in G, 25.3514±0.0014 in BP, and 24.7619±0.0019 in RP (VEGAMAG).

Title:: Gaia DR2-light Cone Search
Short Name:: GDR2light SCS
Date:: 23 Mar 2022 13:13:05
Publisher:: The GAVO DC team
Description:: 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 various Xlite tables) or to make the data more accessible to VO clients (e.g., epoch fluxes). Other Gaia-related data is found in, among others, the gdr2dist, gdr3mock, gdr3spec, gedr3auto, gedr3dist, gedr3mock, and gedr3spur schemas.
