Notes. The columns contain the increasing number (n), the value (fn), the amplitude (A), and the phase (Φ) of each detected frequency that is characterised as independent (i.e. it is not a combination of other frequencies).

The temporal zeropoints for the computation of the phases for each system and per passband were as follows: JD2459180.0 (B, V, I) and JD2459193.0 (TESS) for HM Pup, JD2459025.0 (B, V) and JD2459361.0 (TESS) for V632 Sco, and JD2459325.0 (B, V, I) and JD2459281.0 (TESS) for TT Vel.
