Description:
The astrometry of 16 radio stars taken from the list of Wendker
(1995, Cat. II/199) is presented. The observations were carried out
between 1996.3 and 1998.8 at the Valinhos CCD Meridian Circle. The
results are given on the Hipparcos/Tycho reference frame. The data
obtained relatively to the ACT catalogue is presented here. The ACT
reference stars measured on 16 sky strips are listed on the table
named tableref. The Table 1 of this paper, is presented, giving the
radio star position on each field.
