NOTES

UTC(AUS) is the output of a designated caesium beam standard.
The fractional frequency offset is calculated from the slope of a least squares fit to 2 days of phase data.
A positive value of the fractional frequency offset means that the frequency is high with respect to UTC(AUS).
ADEV is the fractional Allan Deviation (Hz/Hz).
TCXO = temperature compensated crystal oscillator.
OCXO = oven controlled crystal oscillator.
