Quasi-automatic software support for Gaia ground based optical tracking
S. Bouquillon, C. Barache, T. Carlucci +6
The ESA Gaia satellite mission will create a catalog of 1 billion stars with unprecedented astrometric precision. To achieve its aim in terms of astrometric precision, a ground bas…
Characterizing the astrometric precision limit for moving targets observed with digital-array detectors
S. Bouquillon, R. A. Mendez, M. Altmann +5
Aims. We investigate the maximum astrometric precision that can be reached on moving targets observed with digital-sensor arrays, and provide an estimate for its ultimate lower lim…
A 1500 deg Near Infrared Proper Motion Catalogue from the UKIDSS Large Area Survey
L. Smith, P. W. Lucas, B. Burningham +5
The UKIDSS Large Area Survey (LAS) began in 2005, with the start of the UKIDSS program as a 7 year effort to survey roughly 4000 deg at high galactic latitudes in Y, J, H and K…
Parallaxes of Southern Extremely Cool objects (PARSEC) II: Spectroscopic Follow-up and Parallaxes of 52 Targets
F. Marocco, A. H. Andrei, R. L. Smart +8
We present near-infrared spectroscopy for 52 ultracool dwarfs, including two newly discovered late-M dwarfs, one new late-M subdwarf candidate, three new L and four new T dwarfs. W…
The Large Quasar Reference Frame (LQRF) - an optical representation of the ICRS
A. H. Andrei, J. Souchay, N. Zacharias +9
The large number and all-sky distribution of quasars from different surveys, along with their presence in large, deep astrometric catalogs,enables the building of an optical materi…
