Abstract :
A time-scale algorithm. AT1 plus frequency variance, run in postprocessed mode is presented. Such a postprocessed scale can take advantage of better characterization of the clocks in the time-scale ensemble and improved capability for frequency step detection. Real and simulated data are used to show how the algorithm compares with AT1 alone.<>
