A Study of the Parameters of Individual Type-I Bursts

The Dwingeloo 60-channel radio spectrograph has observed at metric wavelengths for a long time. Hundreds of type-I bursts in the digitally recorded solar noise storms were studied and the results are presented in this paper. We hoped to learn more about the emission and propagation of the radiation by trying to find patterns in the dynamic spectra of individual bursts or statistical relations between some of the parameters that can be defined to describe the spectra. The bursts are reduced and represented in a standard way. Graphical representations are inspected by eye and compared qualitatively. Numerical burst parameters are studied statistically. We describe the properties of instantaneous burst spectra. The polarization properties of bursts and the relation between burst- and continuum-polarization are studied to some extent. Apart from these results we find no significant new properties, despite the high quality of the data.
