Proper-Motion Study of the Magellanic Clouds Using SPM Material

reportActive / Technical Report | Accession Number: ADA542963 | Open PDF

Abstract:

Absolute proper motions are determined for stars and galaxies to V 17.5 over a 450 deg2 area that encloses both Magellanic Clouds. The proper motions are based on photographic and CCD observations of the YaleSan Juan Southern Proper Motion program, which span a baseline of 40 years. Multiple, local relative proper-motion measures are combined in an overlap solution using photometrically selected Galactic disk stars to define a global relative system that is then transformed to absolute using external galaxies and Hipparcos stars to tie into the ICRS.
