1103 parallaxes and proper motions from URAT J/AJ/151/160 ivo://CDS.VizieR/J/AJ/151/160 doi:10.26093/cds/vizier.51510160 CDS Finch C.T. Zacharias N. 2018-08-24T08:02:29Z 2016-07-26T07:05:37Z CDS support team CDS, Observatoire de Strasbourg, 11 rue de l'Universite, F-67000 Strasbourg, France cds-question@unistra.fr visible-astronomy trigonometric-parallax proper-motions We present 1103 trigonometric parallaxes and proper motions from the United States Naval Observatory Robotic Astrometric Telescope (URAT) observations taken at the Naval Observatory Flagstaff Station (NOFS) over a three-year period from 2012 April to 2015 June covering the entire sky north of about -10{deg} decl. We selected two samples: previously suspected nearby stars from known photometric distances and stars showing a large, significant parallax signature in URAT epoch data without any prior selection criteria. All systems presented in this paper have an observed parallax {>=}40mas with no previous published trigonometric parallax. The formal errors on these weighted parallax solutions are mostly between 4 and 10mas. This sample gives a significant (of the order of 50%) increase to the number of known systems having a trigonometric parallax to be within 25pc of the Sun (without applying Lutz-Kelker bias corrections). A few of these are found to be within 10pc. Many of these new nearby stars display a total proper motion of less than 200mas/yr. URAT parallax results have been verified against Hipparcos and Yale data for stars in common. The publication of all significant parallax observations from URAT data is in preparation for CDS. 2016AJ....151..160F https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/151/160 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to II/336 : AAVSO Photometric All Sky Survey (APASS) DR9 (Henden+, 2016) I/329 : URAT1 Catalog (Zacharias+ 2015) I/322 : UCAC4 Catalogue (Zacharias+, 2012) J/AJ/149/5 : Solar neighborhood.
