Table A.2.
Flickering measurements in the V, B, and U band. We show the date when the light curve was taken in MJD and calendar date; the amplitude calculated as max-min (see Sect. 3.2); the mean magnitude, band and the source of data. TESS magnitudes were calibrated against contemporaneous I AAVSO observations. The rows are sorted by filter. Data taken during the low-accretion-rate period are highlighted in bold-face. In comparison with other dates, the flickering amplitude during 2019 significantly decreased.
