Top left panel: Sector 5 light curve of HD 34859 (TIC 4070682). This is an ApSi star that shows clear rotational variations with a period of P_rot = 1.046 ± 0.001 d. This is a relatively short rotation period Ap star. Top right panel: amplitude spectrum for the Sector 5 data set for HD 34859 showing the rotational harmonics. Middle left panel: Sector 2 light curve of HD 54399 (TIC 348898673), an ApSr(CrEu) star, showing the clear rotational variations with a period of P_rot = 5.015 ± 0.001 d. This is a typical rotation period Ap star of a few days. Middle right panel: amplitude spectrum for the Sector 1–7 data set for HD 54399 showing the rotational harmonics. The differences in shape and amplitude of the light curves are notable; these are a function of the size of the spots and their geometry with respect to the line of sight. Bottom left panel: Sector 9 light curve of HD 98457 (TIC 57065604), an ApSi star, showing the clear rotational variations with a period of P_rot = 11.5394 ± 0.0003 d. This is still a relatively short rotation period Ap star. Bottom right panel: amplitude spectrum for the Sector 9 data set for HD 98457 showing the rotational harmonics. These rotational light curves are typical for magnetic Ap stars, hence set a standard for the Ap stars to follow that do not show rotational variations. We note that the ordinate scales are different for each star, and note the scales themselves for comparison with the stars to come that do not show rotational variability. The units for the abscissa in the left-hand panels is in BJD−2 400 000.0.
