>itself (10 or 100 K)? It is physically small but the value is unknown. Actuall I can see CTI's the loading effect of the crystal. Are you referring to the impedance(X) of the crystal? If so, it's have an effect on the freq response of the crystal but since we don't know determine how it'll effect any source.
