Hi Tom, Holrum,
 
nice plots, do you have access to the Thunderbolt EFC over that day?
 
Holrum mentioned:
 
"Also,  by looking at the DAC and TEMP plots the temp sensor chip  readings 
ARE used in generating the DAC voltage in GPS locked mode...   "
 
Is there any chance to post these plots?
 
thanks,
Said

I say  all of this -- because of an accident in my lab today. Have a
careful look  at these preliminary plots and tell me what you think.
It shows anything  but a nice one-to-one positive linear relationship
between ambient  temperature and GPSDO  output.
