| Abstract: | The old programme of observations (cf. Beobachtungsergebnisse 1964 and Astronomische Zeit- und Breitenbestimmungen 1965, 1) was modified. The conditions described in Instruction (1956) were used again. As previously (cf. Beobachtungsergebnisse 1964), the stars were selected in respect of the derivation of corrections to the co-ordinates of the stars. The new programme, which has been in use since September of 1978, can be used up to the year 2000. |
