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.

It’s not easy, but it can be done. What's the temperature sensitivity of the typical telco-surplus Rb unit? -- These are my opinions.
