Fig. 1.
Upper panel: observed flux, each segment normalised separately to 1.0, and not corrected for transmission functions. Second panel from top: V/I spectra obtained on 2019 October 7, and null spectra offset by +4% for display purpose. Superposed to the null spectra are the error bars on Stokes V/I. Third and fourth panel from the top: same as the second panel, but for Q/I and U/I, respectively; data obtained on 2019 October 8. Bottom panel: difference between circular polarised spectra obtained on 2019 October 8 and 7, and, offset by +4%, the null spectra obtained on 2019 October 7.
