Expected flickering amplitude in the TESS T band as a function of the effective temperature of the giant companion computed for three distinct accretion disk temperatures (7000 K, 10 000 K, and 13 000 K), assuming an equal integrated flux of the giant and the disk in the Johnson B filter. The cases with flickering amplitudes, A_B, in the Johnson B of 0.1 and 0.01 mag are illustrated by solid and dotted lines, respectively.
