Digitization and astrometric calibration of Carte du Ciel photographic plates with Gaia~DR1
K. Lehtinen, T. Prusti, J. de Bruijne +6
We want to study whether the astrometric and photometric accuracies obtained for the Carte du Ciel plates digitized with a commercial digital camera are high enough for scientific…
Gaia Data Release 2. Calibration and mitigation of electronic offset effects in the data
N. C. Hambly, M. Cropper, S. Boudreault +30
The European Space Agency Gaia satellite was launched into orbit around L2 in December 2013. This ambitious mission has strict requirements on residual systematic errors resulting…
On-orbit performance of the Gaia CCDs at L2
C. Crowley, R. Kohley, N. C. Hambly +19
The European Space Agency's Gaia satellite was launched into orbit around L2 in December 2013 with a payload containing 106 large-format scientific CCDs. The primary goal of the mi…
Gaia Data Release 1. Summary of the astrometric, photometric, and survey properties
Gaia Collaboration, A. G. A. Brown, A. Vallenari +5
At about 1000 days after the launch of Gaia we present the first Gaia data release, Gaia DR1, consisting of astrometry and photometry for over 1 billion sources brighter than magni…
Detecting stars, galaxies, and asteroids with Gaia
J. H. J. de Bruijne, M. Allen, S. Azaz +3
(Abridged) Gaia aims to make a 3-dimensional map of 1,000 million stars in our Milky Way to unravel its kinematical, dynamical, and chemical structure and evolution. Gaia's on-boar…
An Analytical Model of Radiation-Induced Charge Transfer Inefficiency for CCD Detectors
Alexander Short, Cian Crowley, Jos H. J. de Bruijne +1
The European Space Agency's Gaia mission is scheduled for launch in 2013. It will operate at L2 for 5 years, rotating slowly to scan the sky so that its two optical telescopes will…
Science performance of Gaia, ESA's space-astrometry mission
J. H. J. de Bruijne
Gaia is the next astrometry mission of the European Space Agency (ESA), following up on the success of the Hipparcos mission. With a focal plane containing 106 CCD detectors, Gaia…
Gaia broad band photometry
C. Jordi, M. Gebran, J. M. Carrasco +7
The scientific community needs to be prepared to analyse the data from Gaia, one of the most ambitious ESA space missions, to be launched in 2012. The purpose of this paper is to p…
