Variability of LK-Hα-233 in total flux (top left), polarized flux (bottom left), polarization degree (top right), and polarization angle (bottom right) as a function of time (in modified Julian date). We accounted for the three HST/FOC observations; however, due to a pointing error which cut off part of the object in 1994, some data points are unavailable from that epoch. Except for the black crosses (full field of view, 7 × 7 arcseconds), all other points correspond to 1 arcsecond aperture radius integration windows at the five different regions presented in Fig. 6. Error bars are shown but may be too small to be visible.
