Gaia Data Release 2 (Gaia DR2) contains results for 1693 million sources in the magnitude range 3 to 21 based on observations collected by European Space Agency satellite during first 22 months of its operational phase. We describe input data, models, and processing used astrometric content DR2, validation these performed within astrometry task. Some 320 billion centroid positions from pre-processed CCD were estimate five parameters (positions, parallaxes, proper motions) 1332 sources,...
Gaia Early Data Release 3 (Gaia EDR3) contains results for 1.812 billion sources in the magnitude range G = to 21 based on observations collected by European Space Agency satellite during first 34 months of its operational phase. We describe input data, models, and processing used astrometric content EDR3, as well validation these performed within astrometry task. The broadly followed same procedures DR2, but with significant improvements modelling observations. For time data processing,...
Gaia Data Release 1 (Gaia DR1) contains astrometric results for more than billion stars brighter magnitude 20.7 based on observations collected by the satellite during first 14 months of its operational phase. We give a brief overview content data release and model assumptions, processing, validation results. For in common with Hipparcos Tycho-2 catalogues, complete single-star solutions are obtained incorporating positional information from earlier catalogues. other only their positions...
The Guide Star Catalog II (GSC-II) is an all-sky database of objects derived from the uncompressed Digitized Sky Surveys that Space Telescope Science Institute has created Palomar and UK Schmidt survey plates made available to community. Like its predecessor (GSC-I), GSC-II was primarily provide guide star information observation planning support for Hubble Telescope. This version, however, already employed at some ground-based new-technology telescopes such as GEMINI, VLT, TNG, will also be...
Context. The first data release from the Gaia mission contains accurate positions and magnitudes for more than a billion sources, proper motions parallaxes majority of 2.5 million Hipparcos Tycho-2 stars.
Abstract Gaia is an ESA Cornerstone mission, scheduled to be launched in spring 2013, dedicated precisely measure the positions and motions of over a billion stars our galaxy: Milky Way. Data Processing Center Turin (DPCT), Italian DPC, hosted operated at ALTEC Turin. The primary objective DPCT provide infrastructure operations support Astrometric Verification Unit (AVU) activities for CU3 participation data processing tasks. will archive all data, produced delivered DPAC as part...
