Scientific paper

A program to measure trigonometric stellar parallaxes using a charge coupled device (CCD) at the prime focus of the Kitt Peak National Observatory (KPNO) 4-m telescope was started in July 1980. Preliminary parallaxes have been measured for 11 stars. The three prime candidates have uncertainties in the mean position of about 1 milliarcsecond and uncertainties in the parallax of about 2 milliarcseconds. This first paper discusses many of the technical aspects of the program and presents these parallaxes.
