Results from a rigourous Astrometry method in optical astrometry

2003
38 optical counterparts of ICRF sources were observed and positions were deduced using stars extracted from different catalogues (USNO B1.0, USNO A2.0, GSCII...). These positions were compared to the ICRF positions, and to other published positions of the same optical counterparts.
