Extended Data Fig. 3: RM synthesis results of the seven bursts.
From: Diverse polarization angle swings from a repeating fast radio burst source
We calculate the RM spectrum within the range −8,000 to +8,000 rad m−2. The horizontal red shaded area denotes the 1σ interval of the baseline. The vertical red line denotes the best-fit RM value. We also show a zoom-in of the spectral peak, where the vertical orange dashed lines show the range in which the spectrum is used in peak fitting. The best-fitting Gaussian and its 68% confidence interval are indicated by the orange curve and blue shading. The vertical red lines and shading show the best-fit RM and the 68% confidence intervals. We also show the Bayesian RM, indicated by the vertical black lines and shading. The burst number in each sub-plot is defined in Table 1.
