Abstract:
The rotation measures of 555 extragalactic radio sources are
calculated as a result of a large number of new linear polarization
measurements carried out by us at several wavelengths between 1.59
and 10.5GHz. A summary of references for previous polarization
measurements is included, and the procedure for optimizing the number
of unambiguous rotation measures is described.

59- 60 I2 deg e_IPA [0,32] error in IPA
--------------------------------------------------------------------------------
Note on optID: unexplained in the text, but most likely:
G=galaxy, N=N-galaxy, D=D-galaxy, DB=dumb-bell galaxy,
En=elliptical galaxy, Q=quasar, S0=S0 galaxy
SO (=S0 ?), ED and ND are presumably intermediate types
Note on RM: The Faraday rotation measure RM relates the rotation to
wavelength by φ=1/2.RM.λ2
