I've never sat down and made mega accurate measurements, but the spec sheet 
show a straight line for the tunung curve and claims 1%[typ] linearity..
other important things to note is that the tempco and maximum freq are 
higher for the 15V curves - typ tempco =0.03 - 0.06%/'c on 15V.. not great, 
but you could probably use it..
Cheers,
Dan
