[time-nuts] Re: Repeatability of stability measurements

[hans-georg at lehnard.de]

Sorry, this was completely nonsense .. i correct the resolution factor
and forgot the "e" so  i get 4.8828124999999998-11 as factor and scaled
the timelab plots with it. My interpretation is just as stupid. 

The correct Factor is 4.8828124999999998e-11.
