Fourier amplitude spectra of the TESS and BRITE photometry centred on f₁ (top), f₆ (bottom left), and f₇ (bottom right). Bb^⋆ represents the combined blue data obtained with BAb and BLb. BTr14, BTr16, Bb^⋆14, and Bb^⋆16 are the red and blue BRITE data, obtained during the years 2014 and 2016, respectively. The BRITE-blue spectra amplitudes are divided by two for better comparison with the other data. Dashed lines indicate a S/N of three.
