  Outflow angles and bulk Lorentz factors for 43 sources that have proper
motions compiled by Vermeulen & Cohen (1994) are computed on the basis of
Doppler factors and observed apparent motions in the plane of the sky. These
estimates of outflow angles and bulk Lorentz factors are discussed along with
their agreement with orientation unified models of AGN. Intrinsic (i.e. rest
frame) brightness temperatures computed by using the inverse Compton and
equipartition Doppler factor are discussed along with their relevance to the
``Inverse Compton catastrophe''. Intrinsic luminosity densities and
luminosities are presented, and the role of systematic errors is discussed.
These studies are carried out using a sample of 100 compact radio sources
compiled by Ghisellini et al. (1993). Error estimates for previously computed
inverse Compton Doppler factors and equipartition Doppler factors are presented
for these sources, along with a few updates of these Doppler factor estimates.
