Both abscissa scales are logarithmically compressed. The lower picture shows polarization values for right circular polarization with the pre-flare polarization subtracted. At low total flux density, the polarization measurement exhibits more noise. Flux density values are integrated over 0.1 s, leading to an overall integration time of 1.25 ms per bin, whereas polarization values are integrated over 1 s, leading to an overall integration time of 12.5 ms per bin. Both flux and polarization are compressed logarithmically.
Several structures show up in polarization, which disappear in the total flux density measurement.
The top inset shows a sequence of inverted U-bursts, occurring in the impulsive phase. The background picture gives an overview of the total event. Breaks in the spectra are due to missing data. The top inset shows a sequence of U-bursts in the impulsive phase. The middle inset displays a detail of the impulsive phase in the range of 1000 MHz to 3000 MHz, exhibiting small scale emissions.
