[time-nuts] Lady Heather question

[GandalfG8 at aol.com]

I've been running the Windows version of Lady Heather tp make  some 
comparisons between Thunderbolts and Mini-Ts, she cracks her whip just  as firmly 
for the Mini-T:-) and have noticed that, for both, I'm seeing all the  plots 
other than the frequency deviation.
 
If I move the mouse pointer within the plots the individual point  values 
shown includes the values for frequency deviation but the graph  isn't 
visible.
I've noticed that the values are quoted in ppb but the oscillator  
deviation scale is shown in the titles above the plots as being in ppt, parts  per 
trillion?, so wonder if I'm just off scale or if it's not scaling as it  
should?
 
Any advice would be appreciated.
 
regards
