Extended Data Fig. 2: Observed and fitted Stokes parameters Q and U for linear polarization as a function of frequency.
From: Diverse polarization angle swings from a repeating fast radio burst source
a, c, Normalized Stokes parameter Q and fitting residuals. b, d, Normalized Stokes parameter U and fitting residuals. The amplitudes of the oscillation have been normalized using the inferred linear polarization intensity. e, Stokes parameter V normalized by the total intensity in each channel. The grey shaded frequencies are removed before fitting owing to low signal intensities, RFI or band-edge effects. The error bars denote the 68% confidence intervals. The burst number in each subplot is as in Table 1.
