Gaia Data Release 1: The reference frame and the optical properties of ICRF sources
F. Mignard, S. Klioner, L. Lindegren +18
As part of the data processing for Gaia Data Release~1 (Gaia DR1) a special astrometric solution was computed, the so-called auxiliary quasar solution. This gives positions for sel…
Gaia Data Release 1: Astrometry - one billion positions, two million proper motions and parallaxes
L. Lindegren, U. Lammers, U. Bastian +80
Gaia Data Release 1 (Gaia DR1) contains astrometric results for more than 1 billion stars brighter than magnitude 20.7 based on observations collected by the Gaia satellite during…
Gaia Data Release 1, Pre-processing and source list creation
C. Fabricius, U. Bastian, J. Portell +1
The first data release from the Gaia mission contains accurate positions and magnitudes for more than a billion sources, and proper motions and parallaxes for the majority of the 2…
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…
The Gaia mission
Gaia Collaboration
Gaia is a cornerstone mission in the science programme of the European Space Agency (ESA). The spacecraft construction was approved in 2006, following a study in which the original…
Measures of the Earth Obliquity during the 1701 Winter Solstice at the Clementine Meridian Line in Rome
Alexandre Humberto Andrei, Costantino Sigismondi, Veronica Regoli
The great meridian line in the Basilica of Santa Maria degli Angeli in Rome was built in 1701/1702 with the scope of measuring the obliquity of the Earth's orbit in the following e…
