Hal there is not one straight answer, as mentioned before these units are  
intended for commercial applications with large temperature ranges. Most 
have  added frequency compensation using heater current sensing for C field  
adjustment or in the case of the FE  5680A DDS control. Looking close at  the 
5680 you can expect 4 E-11 per 1 C.

What's the temperature  sensitivity of the typical telco-surplus Rb unit?
