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…
Gaia on-board metrology: basic angle and best focus
A. Mora, M. Biermann, A. G. A. Brown +21
The Gaia payload ensures maximum passive stability using a single material, SiC, for most of its elements. Dedicated metrology instruments are, however, required to carry out two f…
The impact of CCD radiation damage on Gaia astrometry: I. Image location estimation in the presence of radiation damage
Thibaut Prod'homme, Berry Holl, Lennart Lindegren +1
The Gaia mission has been designed to perform absolute astrometric measurements with unprecedented accuracy; the end-of-mission parallax standard error is required to be 30 micro-a…
Electrode level Monte Carlo model of radiation damage effects on astronomical CCDs
T. Prod'homme, A. G. A. Brown, L. Lindegren +2
Current optical space telescopes rely upon silicon Charge Coupled Devices (CCDs) to detect and image the incoming photons. The performance of a CCD detector depends on its ability…
