Plasma emission (i.e. emission at about the plasma frequency and twice this frequency) is treated taking into account the effects of the magnetic field on the electron plasma waves, on the conversion processes, and on the escaping radiation. The expected degrees of polarization of the fundamental and second harmonic are calculated in the weak field limit. The results are used to estimate the magnetic field strength B at the 80 MHz level from the observed polarization of type III bursts; the result B < 0·04 G is smaller than previous estimates. The possible importance of electron· cyclotron waves in an application to type I bursts is noted.

I correct typographical errors in the paper Weise (2014). These errors have no effect on the results presented in the paper. I have taken this opportunity to discuss a controversy concerning different frequency factors that appear in the expressions for the cross sections: in Weise (2014) there is a factor (ω/ω ) 2 , whereas in Daugherty and Harding (1986), Herold (1979) and Gonthier et al. (2000) the corresponding factor is ω/ω . Typographical errorsThere are three equations in Sect. 2.3 which have typographical errors. The first equation is Eq. (24), the left hand side of which should have the subscript MM in the same manner that Eq. (22) does. Consequently, Eq. (24) should read as follows:The

“…23 The semi-classical method is a heuristic approach that bypasses the rigorous but tedious perturbation analysis by relying on intuitive reasoning, and the method has been extensively employed in the study of plasma emission by Melrose and the University of Sydney group. [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] Reference 22 establishes the equivalence of the statistical mechanical approach and the semi-classical formalism.…”

The statistical mechanical reformulation of weak turbulence theory for unmagnetized plasmas including fully electromagnetic effects was carried out by Yoon [Phys. Plasmas 13, 022302 (2006)]. However, the wave kinetic equation for the transverse wave ignores the nonlinear three-wave interaction that involves two transverse waves and a Langmuir wave, the incoherent analogue of the so-called Raman scattering process, which may account for the third and higher-harmonic plasma emissions. The present paper extends the previous formalism by including such a term.
