Extended Data Fig. 3: The polarization spectra for the first observed burst from the ARO 10-m telescope.
From: A bright millisecond-duration radio burst from a Galactic magnetar
a–d, The spectrum of the first burst in the Stokes I parameter and its cubic spline-smoothed version (black line) (a), the Stokes Q parameter divided by the total linear polarization, L (b), the Stokes U parameter divided by the total linear polarization (c), and the uncalibrated polarization angle, ψ (d). The frequency channels with greater polarized intensity are indicated with darker points. The best-fit model of the Faraday rotation modulation with an RM of 116 rad m−2 is indicated by the black lines in b and c. The best-fit model of the uncalibrated polarization angle is indicated with the solid red line in d. Error bars are 1σ.
