Notes.Corr. coef. Los Tb (K)

^(*)

Correlation coefficient estimated for radio and magnetic field time-series with zero lag and with the lag for which the highest coefficient.

^(**)

line-of-sight magnetic field component.

^(***)

brightness temperature, taken from solar maps at 37 GHz before and after observations. coefficient – wavelet spectral intervals. FSM – Fourier spectral maxima.
