 ## Performance 
-- Performance values are clock frequency stability (ADEV). Plots are initially drawn using a marker for a 1 second integration time. Longer integration times (1000 and 10,000) are also plotted if and where that information is available. Where there are multiple ADEV integration times, these are connected with a thin vertical line to the 1 sec marker.
