Description:
This is an astrometric catalog, providing positions of 89,422 stars in
398 selected fields of extragalactic reference frame sources. The
stars are mainly in the 11 to 14 magnitude range. The average
positional accuracy is about 50 mas per coordinate at the epoch of
observation, which is between 1976.2 and 1991.9. The observations are
based on photographic plates, taken with 2 telescopes which are:
- the Hamburg Zone astrograph (in the Northern Hemisphere)
- the USNO Twin astrograph at Black Birch (New Zealand)
