Description
The N70E catalogue provides improved mean positions and proper motions for the 718 Basic fundamental stars from the FK5 catalogue in the equatorial zone covering the declination range from -30 to +30 degrees. The catalogue is resulted from revision of the FK5 system on the basis of 36 modern absolute and quasi-absolute catalogues and the four fundamental catalogues FK3, FK4, GC, N30, and revision of FK5 individual positions and proper motions by use of 52 catalogues distributed at the time span from 1900 to 1993. Absolute orientation in space of N70E catalogue is defined by the IAU (1976) system of astronomical constants. Only the machine-readable version of the N70E catalogue is distributed. It contains the positions and proper motions of the stars for the epoch and equinox J2000.0, the mean epochs of individual observed right ascensions and declinations used to determine the final positions, and the mean errors of the final positions and proper motions for the reported epochs.
