Hi
The use of femtoseconds come from the AVAR it's self. It was originally defined
by time domain people. It's delineated by a Tau dimensioned in seconds. The
time domain noise that's 1x10^-12 or 1x10^-15 down at one second does indeed

As with any

I see tau, but does identifying a tau of 1E-14 allow you to say you are
locked to 10fs? The smallest tau I've seen in my E1938 collection is 1E-1.

Hi
While the units are more properly femto seconds/ second you do indeed see 1s
AVAR plots labeled in fS.
