A total of 110000 observations of 26000 stars was obtained between 1967 and 1972. The internal mean errors are 0″.17 and 0″.27 in Δα cosδ and Δδ, respectively, both multiplied by the factor (cosz)−0.5 at the zenith distance z. The preliminary evaluation also shows that the internal systematic errors, judged from the clamp corrections in 5° zones in declination, are less than ± 0.″02 and ± 0.″15, respectively. The systematic differences in right ascension from the FK4 are given.
