cds-question@unistra.frsubdwarf-starsvisible-astronomytrigonometric-parallaxinfrared-photometryproper-motionsWe measure absolute trigonometric parallaxes and proper motions with respect to many background galaxies for a sample of ten ultracool subdwarfs. Observations were taken in the H-band with the OMEGA2000 camera on the 3.5 m-telescope at Calar Alto, Spain during a time period of 3.5-years. For the first time, the reduction of the astrometric measurements was carried out directly with respect to background galaxies. We obtained absolute parallaxes with mean errors ranging between 1 and 3mas.2009A&A...493L..27Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/493/L27CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/124/1190 : Northern high proper motion stars in DSS (Lepine+, 2002)J/ApJ/564/421 : Spectra of T dwarfs.
