Atomic time and the rotation of pulsars.
Abstract
The relationship between the rotation of millisecond pulsars and the atomic clocks is examined with emphasis on possible time scale realizations and on the selection of appropriate time scales to analyze pulsar timing data. It is concluded that, as long as the measurement noise remains at the present level, it will not be possible to use the rotation of millisecond pulsars to enhance the long-term stability of terrestrial time scales below the current level before many more years of data have been obtained. TA(PTB), PTBCS2, or TT(BIPMxx) are recommended as the most suitable of the presently available time scales for the analysis of pulsar timing measurements.
