Atomic time scales for pulsar studies and other demanding applications
Abstract
The International Atomic Time TAI is produced in near real time and definitive when issued in the Annual Report of the Bureau International de l'Heure. Although it satisfies almost all the needs for an accurate time scale, there are some cases where better approximations to an ideal atomic time are required. By combining TAI and the data of the primary cesium standards of the National Research Council of Canada (NRC) and of the Physikalisch-Technische Bundesanstalt of FRG (PTB), the author has established for the interval 1976.0 - 1987.0 an improved atomic time scale. The new scale is usually very close to TA(NRC) and TA(PTB), laboratory time scales, which can also be employed directly for the most demanding application, for some stated intervals.
