stars. The amplitude spectra are shown in échelle format, segments of equal
length being stacked vertically. a, V435 Car; b, HD 55863; c, HD 42608; d,
HD 24975; e, HD 46722; f, HD 220811. The vertical dashed line shows the value of
∆ν used in each case, with a repeated overlap region added on the right for
clarity. The greyscale shows the observed amplitude spectrum of data from the
TESS spacecraft, where the number of 27-day sectors was four for V435 Car,
three for HD 55863, two for HD 24975 and HD 46722, and one for HD 42608 and
HD 220811. Smoothing was applied to the observed amplitude spectra before
plotting, and the red stripes mark overtone sequences of l = 0 and l = 1 modes.
