Example of a light curve (left), a periodogram (centre) and a folded light curve (right) for UCAC4 208-001676 in TESS Sector 1 with the fitted frequency of 1.03 days found by the Lomb-Scargle method. At the centre panel, the period at maximum power, found by the periodogram method, is clearly seen as a peak value. We analysed four sectors of TESS data for this star: 2, 3, 29, 30, 69 and the average period found to be 1.02 days.
