Abstract
Right ascension for Alpha Scorpii A and right ascension and declination for 9 Sagittarii obtained with the astrolabe of Santiago are given in the FK5 system. The average precision is 0.07 arcsec in right ascension and 0.15 arcsec in declination. Other results are given for these radio stars for comparison.
