We have used simultaneous VLBI and ROSAT observations of 3C279 to estimate the doppler factor and angle to the line of sight in the parsec-scale radio ject. The calculations are based on two inverse-Compton scattering models: a homogeneous sphere and an inhomogeneous Konigl jet. We compare our results to those of Unwin et. al. (1994) for another blazar, 3C345.
