Query: Deriving AGN properties from radio CP and LP   We report multi-frequency circular polarization measurements for the radio
source 0056-00 taken at the Effelsberg 100-m radiotelescope. The data reduction
is based on a new calibration procedure that allows the contemporary
measurement of the four Stokes parameters with single-dish radiotelescopes
