		| Abstract: | By combining VLBI and total flux density data it is possible to get an indirect ``look'' at the innermost, unresolved core regions of AGN and to estimate physical parameters such as the intrinsic brightness temperatures, Lorentz factors and viewing angles, unobtainable by either VLBI or multi-frequency flux monitoring alone. |
