Abstract:

Polarization data are presented for 62 B2 radio galaxies. The sources were observed at 6 cm in different configurations of the VLA. The results are given as integrated and mean component parameters. We also present maps of total intensity with superimposed vectors representing the fractional polarization and position angle. We compare these new data with older data at 20 cm and discuss briefly depolarization, rotation of polarization angle and geometry of the magnetic field.
