| Popis: |
Observations of lunar occultations made between 1800 and 1955 are analyzed in order to determine the fluctuations of the Earth’s rotation before the International Atomic Time was established. The reduction is made on the basis of the DE200/LE200 ephemeris and the FK5 system. The analysis of the fluctuations shows a main period of 11.7 lunations caused by the error in the stars places. |
