J/A+A/468/163       Sample of low mass stars with mu>0.1"/yr     (Deacon+, 2007)

Southern infrared proper motion survey. II. A sample of low mass stars with mu>0.1"/yr. Deacon N.R., Hambly N.C. <Astron. Astrophys. 468, 163 (2007)> =2007A&A...468..163D
ADC_Keywords: Stars, nearby ; Proper motions ; Photometry, infrared Keywords: astrometry - stars: low mass, brown dwarfs Abstract: We present details of the second part of the Southern Infrared Proper Motion Survey (SIPS). Here accurate relative astrometry allows us to reduce the minimum proper motion to 0.1"/yr. This yields 6904 objects with proper motions between our minimum cut and half an arcsecond a year. A small overspill sample with proper motions greater than this is also included. We examine our sample to identify interesting individual objects such as common proper motion binaries, potential L dwarfs and candidate nearby stars. Finally we show our survey is incomplete due to many factors, factors which we will take into account when simulating these survey results in the next paper in this series. File Summary:
