A Search for High Proper Motion T Dwarfs with Pan-STARRS1 + 2MASS + WISE
Search Proper Motion Dwarfs
2011/10/13
We have searched ~8200 sq. degs for high proper motion (~0.5-2.7"/year) T dwarfs by combining first-epoch data from the Pan-STARRS1 (PS1) 3-Pi Survey, the 2MASS All-Sky Point Source Catalog, and the W...

Investigation of the errors in SDSS proper-motion measurements using samples of quasars
2011/10/17
We investigate in detail the probability distribution function (pdf) of the proper-motion measurement errors in the SDSS+USNO-B proper-motion catalog of \citet{mun04} using clean quasar samples. The p...

Solar Neighborhood Discovery Proper Motion Stars Southern Sky
2011/10/13
Here we present 1584 new southern proper motion systems with mu > 0.18 "/yr and 16.5 > R_59F > 18.0. This search complements the six previous SuperCOSMOS-RECONS (SCR) proper motion searches of the sou...

PHOTOGRAPHIC ZENITH TUBE OBSERVATIONS TO IMPROVE HIPPARCOS PROPER MOTION IN DECLINATION OF SOME STARS
Astrometry-Reference systems
2009/3/3
in declination for some HIPPARCOS stars are presented. A long
series of optical observations of these stars observed with Photographic Zenith Tubes
(PZT) are used. The HIPPARCOS ESA mission (ESA 199...
